Nursing Elites

1. The settings on a client's synchronized intermittent mandatory ventilation (SIMV) are respiratory rate 12 breaths/minute, tidal volume at 600 mL, FiO2 35%, and positive end-expiratory pressure (PEEP) 5 cm H2O. Which assessment finding necessitates immediate intervention by the nurse?

• A. Bilateral crackles in the lung bases.
• B. Low-pressure indicator alarm.
• C. Oxygen saturation of 91%.
• D. Respiratory rate of 18 breaths/minute.

Correct answer: B

Rationale: A low-pressure alarm may indicate a disconnection or leak in the system, which needs immediate intervention. Bilateral crackles in the lung bases may indicate fluid overload but do not require immediate intervention in this case. An oxygen saturation of 91% is concerning but not as urgent as a potential equipment issue. A respiratory rate of 18 breaths/minute is higher than the set rate but may not necessitate immediate intervention unless accompanied by other distress symptoms.

2. A client with chronic kidney disease is receiving epoetin alfa. Which laboratory value should the nurse monitor to determine the effectiveness of the treatment?

• A. Blood urea nitrogen (BUN)
• B. Serum creatinine
• C. Hemoglobin and hematocrit
• D. Serum potassium

Correct answer: C

Rationale: The correct answer is C: Hemoglobin and hematocrit. Epoetin alfa is a medication that stimulates red blood cell production, so monitoring hemoglobin and hematocrit levels is essential to assess its effectiveness. These values reflect the oxygen-carrying capacity of the blood and can indicate if the treatment is improving anemia related to chronic kidney disease. Choices A, B, and D are incorrect. Blood urea nitrogen (BUN) and serum creatinine are indicators of kidney function, while serum potassium levels are monitored due to electrolyte imbalances commonly seen in kidney disease, but they do not directly reflect the effectiveness of epoetin alfa.

3. What is the most critical initial intervention for a client who is actively seizing?

• A. Restrain the client to prevent injury
• B. Insert an oral airway
• C. Turn the client to the side
• D. Apply soft restraints to the wrists

Correct answer: C

Rationale: The most critical initial intervention for a client who is actively seizing is to turn the client to the side. This action helps maintain an open airway and prevents aspiration during a seizure. Restrain the client to prevent injury (Choice A) is incorrect because restraining a client during a seizure can lead to injury. Inserting an oral airway (Choice B) is not recommended as it can cause injury and is not necessary during an active seizure. Applying soft restraints to the wrists (Choice D) is also not recommended as it can lead to harm and does not address the immediate airway management needed during a seizure.

4. A client is currently receiving an infusion labeled as 5% dextrose injection 500 ml with heparin sodium 25,000 units at 14 mL/hour per pump. A prescription is received to change the rate of the infusion to heparin 1,000 units/hour. How many ml/hour should the nurse program the infusion pump?

• A. 16 ml/hour.
• B. 18 ml/hour.
• C. 20 ml/hour.
• D. 22 ml/hour.

Correct answer: C

Rationale: To deliver 1,000 units/hour from a solution with 25,000 units in 500 ml, the rate should be set to 20 ml/hour. This is calculated by determining that the solution has 50 units/ml (25,000 units / 500 ml = 50 units/ml) and then dividing the required 1,000 units/hour by 50 units/ml, resulting in 20 ml/hour. Therefore, the nurse should program the infusion pump to deliver heparin at 20 ml/hour. Choices A, B, and D are incorrect as they do not align with the calculated rate of 20 ml/hour.

5. A new mother asks the clinic nurse if she must continue giving her baby nystatin for thrush since the white lesions on his tongue have disappeared. What response by the nurse is most appropriate?

• A. No. When the lesions have disappeared, you may stop the nystatin.
• B. Yes. You should continue it for the full 7 days.
• C. No. Thrush is a self-limiting disorder, and nystatin is given for complete treatment.
• D. Yes. The medication should be refilled for a second week of therapy.

Correct answer: B

Rationale: The correct answer is B because nystatin should be given for the full 7 days even if the lesions are no longer present. Continuing the treatment for the prescribed duration ensures complete eradication of the fungal infection. Choice A is incorrect as stopping the medication prematurely may lead to the reoccurrence of thrush. Choice C is inaccurate as nystatin is not just for comfort but for effective treatment. Choice D is incorrect as refilling the medication for a second week without medical advice may lead to unnecessary prolonged use and potential side effects.
