Nursing Elites

1. A client is prescribed digoxin and has a potassium level of 3.0 mEq/L. Which of the following actions should the nurse take?

• A. Administer digoxin without any modifications
• B. Administer the medication at a lower dose
• C. Monitor serum potassium levels
• D. Discontinue the medication if potassium levels rise

Correct answer: A

Rationale: A potassium level of 3.0 mEq/L indicates hypokalemia, which increases the risk of digoxin toxicity. In this case, the nurse should administer the digoxin without any modifications. Lowering the dose (Choice B) may not be necessary if the potassium level is not critically low. Monitoring serum potassium levels (Choice C) is important but should not delay the administration of digoxin. Discontinuing the medication (Choice D) is not the initial action to take unless the potassium levels become severely low and life-threatening.

2. A nurse is preparing a client for a colonoscopy. Which of the following medications should the nurse anticipate the provider to prescribe as an anesthetic for the procedure?

• A. Propofol
• B. Pancuronium
• C. Promethazine
• D. Pentoxifylline

Correct answer: A

Rationale: The correct answer is A, Propofol. Propofol is a short-acting anesthetic medication commonly used to induce moderate sedation for procedures like a colonoscopy. This medication provides rapid onset and recovery, making it an ideal choice for such procedures. Choice B, Pancuronium, is a neuromuscular blocking agent used for muscle relaxation during surgery and would not be appropriate for sedation during a colonoscopy. Choice C, Promethazine, is an antihistamine used for nausea and motion sickness, not for anesthesia. Choice D, Pentoxifylline, is a medication used to improve blood flow in patients with circulation problems and is not indicated for anesthesia during a colonoscopy.

3. A nurse is reviewing the laboratory results for a client who is at 29 weeks of gestation. Which of the following results should the nurse report to the provider?

• A. WBC count 11,000/mm³
• B. Hgb 11.2 g/dL
• C. Hct 34%
• D. Platelets 140,000/mm³

Correct answer: D

Rationale: A platelet count of 140,000/mm³ is at the lower end of the normal range but can be concerning in pregnancy, especially if there are signs of thrombocytopenia or bleeding. Thrombocytopenia in pregnancy can lead to complications such as bleeding during childbirth or excessive bleeding postpartum. The other laboratory values mentioned are within normal ranges for pregnancy and do not typically raise immediate concerns. High WBC counts can be a normal response to pregnancy, hemoglobin levels around 11.2 g/dL and hematocrit levels around 34% are also considered normal in the third trimester.

4. A nurse is caring for a client who is hyperventilating and has the following ABG results: pH 7.50, PaCO2 29 mm Hg, and HCO3- 25 mEq/L. The nurse should recognize that the client has which of the following acid-base imbalances?

• A. Respiratory acidosis
• B. Respiratory alkalosis
• C. Metabolic acidosis
• D. Metabolic alkalosis

Correct answer: B

Rationale: The correct answer is B: Respiratory alkalosis. In this scenario, the client is hyperventilating, leading to excessive elimination of carbon dioxide. As a result, the PaCO2 decreases, causing a decrease in hydrogen ion concentration and an increase in pH, resulting in respiratory alkalosis. Choice A, Respiratory acidosis, is incorrect because the ABG results show a low PaCO2, not an elevated one. Choices C and D, Metabolic acidosis and Metabolic alkalosis, do not align with the ABG results provided, which point towards a respiratory, not metabolic, imbalance.

5. A nurse is assessing four clients for fluid balance. Which of the following clients is exhibiting manifestations of dehydration?

• A. A client who has a urine specific gravity of 1.010.
• B. A client who has a weight gain of 2.2 kg (2 lb) in 24 hr.
• C. A client who has a hematocrit of 45%.
• D. A client who has a temperature of 39°C (102°F).

Correct answer: D

Rationale: The correct answer is D because an elevated temperature is a common manifestation of dehydration. Choices A, B, and C are not indicative of dehydration. A urine specific gravity of 1.010 is within normal range, weight gain suggests fluid overload, and a hematocrit of 45% is also within normal limits and not specifically related to dehydration.
