Correct Answer: C

Rationale: The correct instruction for administering enoxaparin is to pinch the skin before injecting. Pinching the skin helps create a proper fold for subcutaneous injections like enoxaparin, ensuring proper delivery of the medication into the subcutaneous tissue. Choice A is incorrect because enoxaparin should be administered subcutaneously, not into the muscle. Injecting it into the muscle can lead to complications. Choice B is incorrect because massaging the injection site after administration can increase the risk of bleeding or bruising due to the anticoagulant properties of enoxaparin. Choice D is incorrect as it is a general instruction and does not specifically relate to the administration of enoxaparin.

Correct Answer: B

Rationale: The correct process for taking a telephone order from a provider involves reading back the information for accuracy. This step ensures that the order is correctly understood and reduces the risk of errors. While listing patient information (Choice A) is essential, it does not encompass the complete process of verifying the order. Having a witness listen to the order (Choice C) may not always be practical or necessary, as direct verification is more efficient. Writing down the order and following up (Choice D) is not as crucial as the immediate read-back process, which allows for real-time clarification and confirmation.

Correct Answer: C

Rationale: The correct answer is C: Serum potassium. Spironolactone is a potassium-sparing diuretic, meaning it helps the body retain potassium. Therefore, the nurse should monitor the client's serum potassium levels to prevent hyperkalemia, which can be a potential side effect of spironolactone. Monitoring total bilirubin levels (A) is not specifically required for clients taking spironolactone. Urine ketones (B) are not directly influenced by spironolactone use. Platelet count (D) is not typically monitored in clients taking spironolactone.

Correct Answer: A

Rationale: The correct answer is A: Ensure the injection produces a wheal on the skin. A wheal indicates that the PPD has been administered correctly, allowing for the proper interpretation of results. Administering the injection in the client's thigh (choice B) is not the recommended site for PPD administration; it should be administered intradermally. Using an 18-gauge needle (choice C) is unnecessary and not the standard practice for PPD administration as a smaller gauge needle is preferred for intradermal injections. Massaging the site after injection (choice D) can lead to inaccurate results by dispersing the solution, so it is important to avoid touching the site after the injection to prevent altering the test results.

Correct Answer: A

Rationale: The correct intervention to manage fatigue in a client receiving chemotherapy is to encourage the client to take short naps during the day. Fatigue is a common side effect of chemotherapy, and allowing the client to rest can help combat this symptom. Instructing the client to remain on bedrest (Choice B) is not recommended as it may lead to deconditioning and worsen fatigue. Providing a high-calorie diet (Choice C) may be beneficial for overall nutrition but does not directly address fatigue. Encouraging the client to increase activity levels (Choice D) may exacerbate fatigue instead of alleviating it.
