Nursing Elites

1. Which instruction should the nurse provide to an elderly client who is taking an ACE inhibitor and a calcium channel blocker?

• A. Wear long-sleeved clothing when outdoors
• B. Report the onset of sore throat
• C. Eat plenty of potassium-rich food
• D. Change the position slowly

Correct answer: D

Rationale: The correct instruction for an elderly client taking both an ACE inhibitor and a calcium channel blocker is to change positions slowly. Both medications can lead to orthostatic hypotension, a sudden drop in blood pressure when changing positions, which can increase the risk of falls. Instructing the client to change positions slowly helps prevent falls. Wearing long-sleeved clothing when outdoors does not directly relate to the medication combination. Reporting the onset of a sore throat is important for monitoring potential side effects but is not specific to these medications. While potassium levels should be monitored with ACE inhibitors, eating plenty of potassium-rich foods without guidance can lead to hyperkalemia, a potential side effect of ACE inhibitors.

2. The nurse-manager of a perinatal unit is notified that one client from the medical-surgical unit needs to be transferred to make room for new admissions. Which client should the nurse recommend for transfer to the antepartal unit?

• A. A 45-year-old with chronic hepatitis B.
• B. A 35-year-old with lupus erythematosus
• C. A 19-year-old diagnosed with rubella
• D. A 25-year-old with herpes lesions of the vulva

Correct answer: B

Rationale: The correct answer is B because a client with lupus erythematosus can be safely transferred to the antepartal unit as this condition does not pose a significant risk to other patients or staff. Choices A, C, and D should not be recommended for transfer to the antepartal unit due to the potential risks they may pose to pregnant women and their unborn babies. Chronic hepatitis B, rubella, and herpes lesions of the vulva can be contagious and harmful in the perinatal setting.

3. A male client admitted three days ago with respiratory failure is intubated, and 40% oxygen per facemask is initiated. Currently, his temperature is 99°F, capillary refill is less than 4 seconds, and respiratory effort is within normal limits. What outcome should the nurse evaluate to measure for successful extubation?

• A. Exhibits adequate tissue perfusion
• B. Remains free of injury
• C. Remains free of infection
• D. Maintains effective breathing pattern

Correct answer: D

Rationale: Successful extubation relies on the patient's ability to maintain an effective breathing pattern. This indicates that the patient can adequately oxygenate and ventilate without the need for mechanical support. Monitoring tissue perfusion, preventing infection, and ensuring safety are important but not directly related to the immediate criteria for successful extubation. Tissue perfusion, injury prevention, and infection control are crucial aspects of overall patient care but are not the primary factors to consider when evaluating readiness for extubation.

4. The nurse in a community health clinic is interviewing a female client who has three children. The client tells the nurse that she has a new man in her life, with whom she is having a sexual relationship, and that they both smoke cigarettes. Which information is most important for the nurse to provide this client?

• A. Oral contraceptives should be started to prevent an unwanted pregnancy
• B. Children are more prone to upper respiratory infections if exposed to smoke at home
• C. Cigarette smoking increases the risk for peptic ulcers and emphysema
• D. A diaphragm and condom provide effective contraception when used together

Correct answer: D

Rationale: The most important information for the nurse to provide the client in this situation is that using both a diaphragm and a condom together provides effective contraception and also protects against sexually transmitted diseases (STDs). While oral contraceptives can help prevent unwanted pregnancies, using a barrier method like a diaphragm and a condom is crucial in this scenario where the client is engaging in a new sexual relationship. Choice B is important information but is not the top priority in this context. Choice C, although relevant, does not address the immediate concern of contraception and STD prevention. Therefore, the correct answer is D.

5. A client who has a new prescription for warfarin (Coumadin) asks the nurse how the medication works. What explanation should the nurse provide?

• A. It dissolves blood clots
• B. It prevents the blood from clotting
• C. It thins the blood
• D. It decreases the risk of infection

Correct answer: B

Rationale: The correct answer is B: 'It prevents the blood from clotting.' Warfarin works by inhibiting the synthesis of vitamin K-dependent clotting factors in the liver, thereby preventing the formation of blood clots. Choice A is incorrect because warfarin does not dissolve existing blood clots but prevents new ones from forming. Choice C is partially correct but not as specific as choice B in explaining how warfarin works. Choice D is unrelated to the mechanism of action of warfarin and is incorrect.
