1. Heparin 20,000 units in 500 ml D5W at 50 ml/hour has been infusing for 5.5 hours. How much heparin has the client received?

• A. 11,000 units.
• B. 13,000 units.
• C. 15,000 units.
• D. 17,000 units.

Correct answer: A

Rationale: To calculate the total amount of heparin received, multiply the infusion rate (50 ml/hour) by the total infusion time (5.5 hours). This results in 275 ml of the solution infused. Since there are 20,000 units of heparin in 500 ml, there are 800 units per ml. Therefore, 275 ml contains 220,000 units. However, the heparin is diluted in 500 ml, so the client has received half of this amount, which is 110,000 units. Therefore, the correct answer is 11,000 units. Choices B, C, and D are incorrect as they do not reflect the correct calculation based on the provided information.

2. A healthcare professional is planning to collect a liquid stool specimen from a client for ova and parasites. Inaccurate test results may result if the healthcare professional:

• A. Refrigerates the collected specimen
• B. Collects the specimen in a sterile container
• C. Delays the collection of the specimen
• D. Uses a non-contaminated collection container

Correct answer: A

Rationale: Refrigeration can kill the ova and parasites present in the stool specimen, leading to inaccurate test results. Storing the specimen in a cold environment can disrupt the integrity of the parasites and ova, affecting the accuracy of the test. Collecting the specimen in a sterile container (Choice B) is the correct procedure to prevent external contamination. Delaying the collection of the specimen (Choice C) may affect the freshness of the sample but does not directly impact the test results. Using a non-contaminated collection container (Choice D) is essential to maintain the sample's integrity but does not relate to the risk of killing ova and parasites through refrigeration.

3. A client with a terminal illness is being cared for by a nurse. Which of the following findings indicates that the client's death is imminent?

• A. Cold extremities
• B. Increased appetite
• C. Elevated blood pressure
• D. Increased level of consciousness

Correct answer: A

Rationale: Cold extremities are a common sign observed in clients nearing death. This occurs due to decreased blood circulation as the body's systems begin to shut down. Cold extremities indicate poor perfusion and reduced function of vital organs. Increased appetite (Choice B) is not typically seen in clients approaching death; instead, a decreased appetite is more common. Elevated blood pressure (Choice C) is not a typical finding in clients nearing the end of life, as blood pressure tends to decrease. An increased level of consciousness (Choice D) is also not indicative of imminent death, as clients near death often experience decreased level of consciousness or become unresponsive.

4. A nurse in a provider's office is preparing to assess a young adult client's musculoskeletal system as part of a comprehensive physical examination. Which of the following findings should the nurse expect?

• A. Concave thoracic spine posteriorly
• B. Exaggerated lumbar curvature
• C. Concave lumbar spine posteriorly
• D. Exaggerated thoracic curvature

Correct answer: B

Rationale: When assessing a young adult's musculoskeletal system, the nurse should expect an exaggerated lumbar curvature (lordosis). This is a normal finding in young adults due to the natural curvature of the spine. Concave thoracic spine posteriorly (choice A) and concave lumbar spine posteriorly (choice C) are not typical findings as the spine should have normal curvatures. Exaggerated thoracic curvature (choice D) is also not a typical finding in young adults.

5. When changing the client's dressing, which observation should the nurse report to the client's surgeon for a client recovering from an appendectomy for a ruptured appendix with a surgical wound healing by secondary intention?

• A. A halo of erythema on the surrounding skin
• B. Presence of serous drainage
• C. Edema around the wound
• D. Absence of granulation tissue

Correct answer: A

Rationale: A halo of erythema on the surrounding skin may indicate an infection or inflammation of the wound site, which is critical to report to the surgeon. Erythema, redness, and warmth are signs of inflammation that could potentially be a sign of an infected wound. Serous drainage is a common and expected finding in healing wounds, indicating a normal healing process. Edema around the wound might be expected due to the body's response to tissue injury. The absence of granulation tissue in a wound healing by secondary intention may not be an immediate concern as it forms during the later stages of wound healing.
