Correct Answer: B

Rationale: To assess for an S3 heart sound, the nurse should listen with the bell of the stethoscope. An S3 heart sound is often low-pitched and best heard with the bell. Choice A is incorrect because switching to the diaphragm is not ideal for detecting low-pitched sounds like an S3. Choice C is incorrect as the S3 heart sound is best heard over the apex of the heart, not the aortic area. Choice D is incorrect because moving to the apical area is appropriate, but the nurse should specifically use the bell of the stethoscope to listen for S3 sounds.

Correct Answer: C

Rationale: The correct answer is to palpate the abdomen. When a client abruptly stops taking prednisone, there is a risk of adrenal insufficiency, which can present with symptoms like fatigue. Palpating the abdomen is crucial to assess for signs of adrenal crisis, such as abdominal pain, which can indicate severe adrenal insufficiency. Auscultating breath sounds (Choice A) and observing the skin for bruising (Choice D) are not the priority interventions in this situation. While measuring vital signs (Choice B) is important, palpating the abdomen takes precedence in this case to assess for potential adrenal insufficiency.

Correct Answer: A

Rationale: The nurse's signature on a surgical consent form signifies that the client voluntarily grants permission for the procedure to be done. This is the correct answer because the nurse's signature does not imply the client's competence, understanding of risks and benefits, or that the client signed the form freely and voluntarily. The nurse's role is to verify that the client has made an informed decision and is providing consent for the procedure.

Correct Answer: D

Rationale: The correct answer is D: "I need to get the client's written consent before I release any information to you." In this scenario, the nurse must obtain the client's written consent before disclosing any information to the social worker. This process ensures compliance with privacy laws like HIPAA, which are designed to protect client confidentiality. Choice A is incorrect because it does not address the need for consent. Choice B is incorrect as it is unprofessional and does not focus on obtaining consent. Choice C is incorrect as it suggests information can be shared without consent, which goes against privacy laws.

Correct Answer: B

Rationale: Prothrombin time (PT) is the correct laboratory value to monitor to assess the therapeutic effect of warfarin. Warfarin works by inhibiting clotting factors, and PT measures the time it takes for blood to clot. Monitoring PT helps ensure that the medication is working effectively to prevent clot formation without causing excessive bleeding. Platelet count (Choice A) is not specific to warfarin therapy and assesses the number of platelets in the blood. White blood cell count (Choice C) and hemoglobin level (Choice D) are not directly related to monitoring the therapeutic effect of warfarin.
