Correct Answer: A

Rationale: Correctly assessing a patient with potential pneumonia involves listening to lung sounds and monitoring oxygen saturation. Lung sounds can reveal abnormal breath sounds associated with pneumonia, such as crackles or diminished breath sounds. Oxygen saturation monitoring helps in detecting respiratory distress, a common complication of pneumonia. Monitoring for fever and sputum production (Choice B) is important but not as specific as assessing lung sounds and oxygen saturation. Auscultating heart sounds and checking for cyanosis (Choice C) are not primary assessments for pneumonia. Monitoring for chest pain and administering oxygen (Choice D) are relevant interventions but do not address the initial assessment of pneumonia.

Correct Answer: D

Rationale: The correct action the nurse should take when administering enoxaparin subcutaneously is to pinch the skin between the thumb and forefinger. Pinching the skin helps to lift the subcutaneous tissue, reducing the risk of injecting into the muscle. Choices A, B, and C are incorrect. Choice A is not relevant as the injection site for enoxaparin is typically in the abdomen or thigh, not the arm. Choice B is incorrect as pulling the skin laterally is not a recommended technique for subcutaneous injections. Choice C is also incorrect as massaging the injection site after administration can increase the risk of bleeding or bruising.

Correct Answer: B

Rationale: The correct answer is B. The nurse should inform the client that their oncologist might prescribe a cold cap during treatment to reduce chemotherapy-induced hair loss by cooling the scalp. Choice A is incorrect as washing the hair during treatment is generally recommended. Choice C is incorrect as sunscreen is not typically needed for the scalp in this context. Choice D is incorrect as regrowth of hair can vary among individuals and is not guaranteed within a specific timeframe.

Correct Answer: C

Rationale: The correct answer is C: 'Take up to three tablets during a single angina episode.' Nitroglycerin can be taken up to three times during an episode to relieve angina. Choice A is incorrect because the client should place the tablet under the tongue and wait for it to dissolve, not wait for 10 minutes. Choice B is incorrect because taking up to five tablets during an angina episode is excessive and not recommended. Choice D is incorrect because nitroglycerin tablets are meant to be taken sublingually, not swallowed.

Correct Answer: A

Rationale: When assessing a patient with suspected stroke symptoms, it is crucial to check for facial drooping as it can be a sign of facial nerve weakness, which is a common indicator of stroke. While monitoring speech difficulties and evaluating arm weakness are also important assessments in stroke cases, they are secondary to facial drooping. Checking for the time of onset of symptoms is essential to determine eligibility for time-sensitive treatments like thrombolytic therapy, but when prioritizing assessments, facial drooping takes precedence.
