RN HESI Exit Exam Capstone
1. A client who has been prescribed multiple antihypertensive medications experiences syncope and has a blood pressure of 70/40. What is the rationale for the nurse to hold the next scheduled antihypertensive dose?
- A. Increased urinary clearance of the medications has produced diuresis, lowering the blood pressure.
- B. The antagonistic interaction of the medications has reduced their effectiveness.
- C. The synergistic effect of the medications has resulted in drug toxicity, causing hypotension.
- D. The additive effect of the medications has lowered the blood pressure too much.
Correct answer: D
Rationale: The additive effect of multiple antihypertensive medications can cause hypotension, leading to dangerously low blood pressure. In this scenario, the client experiencing syncope with a blood pressure of 70/40 indicates severe hypotension, likely due to the combined action of the antihypertensive medications. Holding the next scheduled dose is essential to prevent further lowering of blood pressure and potential complications. Choices A, B, and C provide inaccurate explanations and do not align with the client's presentation and the need to manage hypotension caused by the additive effect of the medications.
2. Which medication should the nurse withhold if the client's serum potassium level is 6.2 mEq/L?
- A. Losartan
- B. Spironolactone
- C. Metoprolol
- D. Furosemide
Correct answer: B
Rationale: The correct answer is B: Spironolactone. Spironolactone is a potassium-sparing diuretic that can lead to hyperkalemia. With potassium levels already elevated at 6.2 mEq/L, withholding Spironolactone is essential to prevent further increase in potassium levels, which could result in dangerous cardiac arrhythmias. Losartan (Choice A) is an angiotensin receptor blocker and does not directly affect potassium levels. Metoprolol (Choice C) is a beta-blocker and also does not impact potassium levels significantly. Furosemide (Choice D) is a loop diuretic that can actually lower potassium levels, so it would not be the medication to withhold in this case.
3. The nurse is providing discharge teaching to a client with asthma. Which statement indicates the client understands how to use a rescue inhaler?
- A. I will use my rescue inhaler every morning to prevent asthma attacks.
- B. I should use my rescue inhaler when I start to experience wheezing.
- C. I will use my rescue inhaler when my peak flow meter reading is in the green zone.
- D. I will only use my rescue inhaler before going to bed.
Correct answer: B
Rationale: The correct answer is B: 'I should use my rescue inhaler when I start to experience wheezing.' A rescue inhaler is used during the onset of asthma symptoms, such as wheezing, to quickly open the airways. It is not intended for routine daily use or prevention, which is the role of a maintenance inhaler. Option A is incorrect because a rescue inhaler is not used for prevention but for immediate relief during an asthma attack. Option C is incorrect because the peak flow meter reading is used to monitor asthma control, not to determine when to use a rescue inhaler. Option D is incorrect because using a rescue inhaler only before going to bed does not address the need for immediate relief when wheezing or experiencing asthma symptoms.
4. A client was just taken off the ventilator after surgery and has a nasogastric tube draining bile-colored liquids. Which nursing measure will provide the most comfort to the client?
- A. Allow the client to melt ice chips in the mouth
- B. Provide mints to freshen the breath
- C. Perform frequent oral care with a tooth sponge
- D. Swab the mouth with glycerin swabs
Correct answer: C
Rationale: Performing frequent oral care with a tooth sponge is the most appropriate nursing measure in this scenario. This helps maintain comfort and prevent dryness in clients with nasogastric tubes. Allowing the client to melt ice chips in the mouth may not address oral care needs effectively. Providing mints to freshen the breath is not the priority when the client needs oral care. Swabbing the mouth with glycerin swabs may not be as effective as performing thorough oral care with a tooth sponge.
5. A client has altered renal function and is being treated at home. The nurse recognizes that the most accurate indicator of fluid balance during the weekly visits is?
- A. Difference in the intake and output
- B. Changes in the mucous membranes
- C. Skin turgor
- D. Weekly weight
Correct answer: D
Rationale: In clients with altered renal function being treated at home, weekly weight is the most accurate indicator of fluid balance. Fluid retention or loss can significantly affect weight, making it a reliable measure. Choices A, B, and C are not as accurate indicators of fluid balance as weekly weight. Intake and output differences can vary in accuracy and may not capture all aspects of fluid balance. Changes in mucous membranes and skin turgor can be influenced by factors other than fluid balance, making them less precise indicators.
