Correct Answer: A

Rationale: The correct location to auscultate the pulmonary valve is the second intercostal space at the left sternal border. This area is where the pulmonary valve can best be heard due to its anatomical position. Choice B, the fifth intercostal space at the midclavicular line, is the location for auscultating the mitral valve. Choice C, the fourth intercostal space at the left sternal border, is the area for the tricuspid valve. Choice D, the fifth intercostal space at the left anterior axillary line, is the site for listening to the mitral valve as well. Therefore, option A is the correct choice for auscultating the pulmonary valve.

Correct Answer: B

Rationale: Enoxaparin should be administered with the needle at a 90-degree angle to ensure proper subcutaneous delivery. Choice B is correct as it aligns with the recommended angle for subcutaneous injections. Administering enoxaparin at a 45-degree angle (Choice A), 30-degree angle (Choice C), or 15-degree angle (Choice D) would not be appropriate and may lead to improper administration or absorption of the medication.

Correct Answer: A

Rationale: The correct answer is A because the client's statement indicates a misunderstanding about the need to lie still during the bronchoscopy procedure. The client actually needs to remain still for the procedure to ensure its accuracy and safety. Choices B, C, and D demonstrate an understanding of the procedure by acknowledging the local anesthetic for discomfort, the possibility of receiving medicine for relaxation, and the requirement to fast before the procedure, respectively.

Correct Answer: B

Rationale: The correct instruction is to puncture the site after cleansing and before the antiseptic dries. This sequence helps ensure proper blood collection without introducing contaminants. Choice A is incorrect because wearing sterile gloves is not necessary for capillary blood glucose testing. Choice C is incorrect as wiping the puncture site can introduce contaminants and alter the blood sample. Choice D is incorrect as holding the finger below the heart level is not required for a capillary blood glucose test.

Correct Answer: D

Rationale: The correct course of action for the nurse is to determine which staff members have already been fitted for particulate filter masks before changing assignments. This ensures safety and compliance with infection control protocols. Option A is incorrect as wearing a standard face mask before being fitted for a filter mask does not address compliance with droplet precautions. Option B is incorrect because the priority is to ensure all staff members have appropriate equipment before providing care. Option C is incorrect as a standard mask may not offer sufficient protection when dealing with clients under droplet precautions.
