Question 1.
A 47-year-old patient reports urinary leakage when coughing, laughing, and lifting objects. During examination, the patient demonstrates an appropriate pelvic floor contraction but releases the contraction slowly and has difficulty coordinating the contraction with increased intra-abdominal pressure. Which impairment is most relevant to the patient’s functional complaint?A. Reduced pelvic floor muscle coordination during pressure changes
B. Excessive hip external rotation strength
C. Reduced thoracic mobility during quiet breathing
D. Increased resting ankle plantarflexor activityCorrect Answer. A.
Explanation:
Urinary leakage associated with coughing, laughing, and lifting can be influenced by the ability of the pelvic floor system to respond appropriately to increases in intra-abdominal pressure. In this case, the patient can contract the pelvic floor but demonstrates difficulty coordinating the contraction and relaxation response. This suggests that timing and coordination may be more clinically relevant than simply measuring contraction strength. Treatment decisions should be based on the complete examination rather than assuming weakness is the only impairment. The clinician should also consider breathing strategy, functional movement, bladder habits, symptom behavior, and other factors that may contribute to leakage.Question 2.
A 55-year-old patient with chronic constipation reports prolonged straining and a sensation of incomplete evacuation. During assessment, the patient has difficulty relaxing the pelvic floor when attempting to simulate defecation. Which finding is most relevant to the patient’s bowel symptoms?A. Excessive pelvic floor relaxation during coughing
B. Inability to appropriately relax the pelvic floor during attempted evacuation
C. Increased quadriceps endurance during repeated sit-to-stand activity
D. Reduced shoulder internal rotationCorrect Answer. B.
Explanation:
Normal defecation requires coordinated relaxation of the pelvic floor and appropriate changes in abdominal and rectal pressures. Difficulty relaxing the pelvic floor during attempted evacuation can contribute to obstructed defecatory patterns and a sensation of incomplete emptying. The finding should be interpreted alongside bowel frequency, stool consistency, toileting behavior, abdominal symptoms, medications, diet, and other relevant factors. A strong pelvic floor contraction alone does not establish the cause of constipation. Similarly, unrelated strength or range-of-motion findings do not explain the patient’s primary bowel complaint. The clinical assessment should determine whether impaired coordination is contributing to the functional problem.Question 3.
A 39-year-old patient with persistent pelvic pain reports that symptoms increase after prolonged sitting and improve somewhat with movement. Examination reveals limited hip mobility and reproduction of familiar symptoms during specific hip movements. Which approach is most appropriate when developing the initial treatment plan?A. Treat the pelvic floor exclusively without considering hip function
B. Address relevant musculoskeletal impairments while monitoring their relationship to the patient’s symptoms
C. Recommend complete bed rest until the pain disappears
D. Assume the symptoms are entirely visceral because the pain is located in the pelvisCorrect Answer. B.
Explanation:
Pelvic pain can involve multiple contributing factors, and musculoskeletal impairments may be relevant when symptoms are reproduced or modified by specific movement patterns. Limited hip mobility and symptom reproduction during hip movement provide findings that should be considered during evaluation and treatment planning. This does not prove that the hip is the sole source of the patient’s pain. Pelvic pain can involve musculoskeletal, visceral, neurological, hormonal, and psychosocial factors, so the clinician should maintain an appropriately broad differential. Complete bed rest is generally not an appropriate response to chronic musculoskeletal symptoms and may contribute to further functional limitation.Question 4.
A patient six months after breast cancer treatment develops swelling and tightness in the affected arm. The patient reports that the swelling becomes more noticeable by the end of the day. Which additional finding would be most important when determining whether the presentation requires further medical assessment?A. A new area of unexplained redness and warmth accompanied by systemic symptoms
B. Mild fatigue after household activities
C. Stable shoulder range of motion
D. A preference for wearing loose clothingCorrect Answer. A.
Explanation:
New redness and warmth accompanied by systemic symptoms can indicate an acute medical issue such as infection and should not automatically be attributed to chronic lymphedema. A patient with a history of cancer treatment and lymphatic disruption may have an increased risk of complications affecting the involved limb. The clinician should recognize changes that warrant further evaluation rather than proceeding with routine management without investigation. Fatigue, stable shoulder mobility, and clothing preference may be relevant to overall care but do not carry the same immediate concern. Appropriate screening and communication are essential when a patient’s presentation changes unexpectedly.Question 5.
A postpartum patient wants to return to recreational running but reports pelvic pressure and urinary leakage during high-impact activity. Basic daily activities are comfortable, but symptoms appear during jogging and jumping. Which component should be prioritized when determining readiness for progression?A. The patient’s ability to perform the desired activity without reproducing significant symptoms
B. The patient’s ability to hold a single pelvic floor contraction for as long as possible
C. The patient’s resting heart rate while seated
D. The patient’s upper-extremity flexibilityCorrect Answer. A.
Explanation:
Return to high-impact activity should consider the patient’s specific functional goals and symptom response during progressively demanding tasks. A patient may tolerate daily activities yet experience pelvic pressure or urinary leakage with running and jumping because these activities create greater mechanical and intra-abdominal demands. Readiness should therefore be evaluated using relevant functional tasks rather than relying solely on isolated muscle performance. Pelvic floor strength may be one component of the assessment, but endurance, coordination, pressure management, movement strategy, symptom behavior, and overall load tolerance may also matter. Progression should be individualized according to examination findings and patient goals. -

ASCM CPIM Practice Test
$39.75Add to cartSample Questions and Answers
1. A manufacturer notices that customer orders have become less predictable, causing frequent changes to its production schedule. Which action would BEST help the company improve its demand planning process?
A. Increase finished-goods inventory for every product
B. Analyze historical demand alongside current market and customer information
C. Reduce communication between sales and operations
D. Eliminate safety stock to reduce carrying costsCorrect Answer. B. Analyze historical demand alongside current market and customer information
Explanation: Effective demand planning combines historical patterns with current information rather than relying on one source alone. Historical demand can reveal trends, seasonality, and variability, while current customer, market, and business information can identify changes that historical data cannot capture. Simply increasing inventory may hide the underlying forecasting problem and increase carrying costs. Eliminating safety stock could make service performance worse when demand varies. CPIM planning principles emphasize aligning demand information with supply decisions so that production, inventory, and capacity can respond appropriately to expected requirements.
2. A company uses material requirements planning (MRP) and discovers that several planned production orders require more capacity than a critical work center can provide during the same period. What should the planner do FIRST?
A. Ignore the capacity constraint because MRP automatically resolves all capacity issues
B. Review the planned orders and capacity requirements against the available capacity
C. Increase finished-goods inventory immediately
D. Cancel all orders scheduled for the work centerCorrect Answer. B. Review the planned orders and capacity requirements against the available capacity
Explanation: MRP determines material requirements and planned order timing, but planners must also evaluate whether sufficient capacity exists to execute those plans. When a work center is overloaded, the first step is to identify the magnitude and timing of the capacity constraint by comparing required capacity with available capacity. The planner can then consider alternatives such as rescheduling, adjusting lot sizes, using alternate resources, or changing priorities. Immediately increasing inventory or canceling orders does not address the underlying capacity issue. Understanding the relationship between material plans and available production capacity is an important part of effective supply planning.
3. An organization is reviewing its inventory policy for a component with highly variable demand and unreliable supplier lead times. Which inventory strategy would BEST protect against unexpected shortages?
A. Eliminate safety stock
B. Maintain safety stock based on relevant demand and supply variability
C. Order the same quantity regardless of demand or lead-time conditions
D. Reduce the reorder point whenever supplier reliability decreasesCorrect Answer. B. Maintain safety stock based on relevant demand and supply variability
Explanation: Safety stock provides protection against uncertainty in demand, supply, or lead time. When both demand and supplier lead time are variable, the company faces a greater risk of stockouts if inventory policies do not account for that uncertainty. Safety-stock decisions should consider the desired service level and the variability affecting replenishment. Simply ordering a fixed quantity does not necessarily provide adequate protection, while reducing the reorder point when supplier reliability worsens would generally increase shortage risk. A sound inventory policy balances service requirements with the cost of carrying additional inventory.
4. During an S&OP meeting, sales forecasts indicate strong demand growth while operations reports limited production capacity. What is the PRIMARY purpose of discussing these differences during the S&OP process?
A. Allow each department to create its own independent plan
B. Align demand and supply decisions with the organization’s business objectives
C. Replace the financial planning process entirely
D. Ensure production always follows the original sales forecastCorrect Answer. B. Align demand and supply decisions with the organization’s business objectives
Explanation: Sales and operations planning provides a cross-functional process for balancing expected demand with available supply and resources. When sales forecasts exceed production capacity, the organization can evaluate alternatives such as capacity adjustments, inventory changes, prioritization, sourcing decisions, or demand-management actions. The purpose is not for one department to automatically control the final plan but to create an integrated decision that supports business objectives. S&OP connects demand, supply, operations, and financial considerations so management can make informed decisions when resources and market requirements do not align.
5. A planner is evaluating two suppliers for the same component. Supplier A offers a lower purchase price but has frequent late deliveries, while Supplier B costs slightly more but consistently meets lead-time commitments. Which factor should the planner consider MOST carefully when making the sourcing decision?
A. Purchase price alone
B. The supplier’s impact on total supply chain performance and risk
C. The supplier’s location without considering performance
D. The number of purchase orders previously issuedCorrect Answer. B. The supplier’s impact on total supply chain performance and risk
Explanation: Supplier selection should consider more than the quoted purchase price. Frequent late deliveries can create production disruptions, emergency transportation costs, excess safety stock, and customer-service problems. A supplier with a slightly higher price may provide greater reliability and lower overall supply chain risk. Planners should evaluate factors such as quality, delivery performance, lead time, flexibility, total cost, and the supplier’s ability to support operational requirements. CPIM concepts emphasize evaluating supply decisions within the broader supply chain rather than optimizing one cost element while creating problems elsewhere.
