Correct Answer: A

Rationale: An aPTT of 75 seconds indicates that heparin therapy is within the therapeutic range for a client with DVT. The activated partial thromboplastin time (aPTT) is used to monitor heparin therapy's effectiveness. Choice B, INR 1.2, is not the correct answer because INR is used to monitor the effectiveness of warfarin, a different anticoagulant, not heparin. Choice C, Hemoglobin 10 g/dL, is not a measure of heparin therapy effectiveness. Choice D, Fibrinogen level 350 mg/dL, is not a specific indicator of heparin therapy effectiveness for DVT.

Correct Answer: C

Rationale: The correct action the nurse should take when administering a cleansing enema is to hold the container of the enema solution 61 cm (24 in) above the client. This height facilitates the proper flow of the solution into the client's rectum. Positioning the client on their left side helps facilitate the administration process, but it is not the specific action related to the enema solution. Inserting the enema tubing 8 cm (3.1 in) into the rectum is incorrect as it may not deliver the solution effectively. Advancing the enema tubing 15 cm (6 in) into the client's rectum is excessive and could cause trauma.

Correct Answer: C

Rationale: The correct action for the nurse to take is to administer naloxone if the client's respiratory rate falls below 10/min. Naloxone is used to reverse opioid-induced respiratory depression, which is a life-threatening situation. Monitoring the client's blood pressure every 4 hours (Choice A) is not the priority in this scenario as respiratory depression requires immediate attention. Asking the client to rate their pain every 2 hours (Choice B) is important for pain management but addressing respiratory depression takes precedence. Evaluating the client's use of the PCA every 4 hours (Choice D) is a routine nursing intervention but does not directly address the urgent need to reverse respiratory depression in this case.

Correct Answer: B

Rationale: The correct action for the nurse to take when preparing to perform postmortem care is to remove the client's IV lines. This step is essential to help maintain the dignity and appearance of the body. Placing the client's dentures in a labeled container (Choice A) is not a priority during postmortem care as the focus is on the body's preparation. While positioning the body in a semi-fowler's position (Choice C) or lowering the client's head of the bed (Choice D) are common practices for living clients to prevent aspiration, they are not necessary after death. Therefore, the immediate action of removing IV lines is most appropriate in this situation.

Correct Answer: C

Rationale: The correct action for the nurse to take is to ensure that the newborn wears a diaper. This is important to prevent irritation during phototherapy, as exposure to light can increase the risk of skin breakdown. Feeding the infant glucose water is unnecessary and not indicated for jaundice treatment. Keeping the infant's head uncovered allows the light to reach the skin effectively. Applying lotion to the newborn every 4 hours can interfere with the effectiveness of phototherapy and is not recommended.
