Correct Answer: C

Rationale: The correct answer is C. Clients with hypertension should ideally avoid or limit alcohol intake rather than just restricting it to weekends. Excessive alcohol consumption can raise blood pressure and interfere with the effectiveness of hypertension management. Choices A, B, and D are all positive statements that align with managing hypertension: reducing salt intake, regular exercise, and monitoring blood pressure are all beneficial lifestyle changes for individuals with hypertension. Therefore, the statement about drinking alcohol only on weekends requires further teaching to emphasize the importance of reducing alcohol consumption for better blood pressure control.

Correct Answer: D

Rationale: When the nurse observes a student nurse making a mistake during a procedure, such as not aspirating before administering a medication, the nurse should provide immediate, discreet feedback to correct the error. Walking up and whispering in the student's ear to stop, aspirate, and then inject is appropriate as it corrects the mistake while maintaining the student's dignity and confidence. Option A is not as effective as it indirectly addresses the issue. Option B is not the best approach as the student needs immediate correction. Option C is not ideal as loudly stating the mistake may embarrass the student and is not necessary for a discreet correction.

Correct Answer: A

Rationale: The correct action for the nurse to take when caring for a client with Clostridium difficile in contact isolation is to wear gloves when changing the client's gown. Clostridium difficile is highly transmissible, and wearing gloves helps prevent the spread of the infection. Using hand sanitizer after contact with the client (Choice B) is not enough to prevent the transmission of C. difficile, as the spores can persist and spread. Wearing a mask when entering the client's room (Choice C) is not necessary for C. difficile transmission, which primarily occurs through contact with contaminated surfaces. Cleaning the room with a disinfectant spray (Choice D) is important, but wearing gloves during direct care is the priority to prevent the nurse from acquiring and spreading the infection.

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: 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.
