Nursing Elites

1. A nurse is reviewing laboratory results for a client who has chronic kidney disease. Which of the following findings should the nurse expect?

• A. Hypernatremia
• B. Hypocalcemia
• C. Low potassium
• D. Low magnesium

Correct answer: B

Rationale: In chronic kidney disease, the kidneys have impaired ability to activate vitamin D, leading to decreased production of calcitriol. Calcitriol is essential for calcium absorption in the intestines. Therefore, hypocalcemia is a common finding in chronic kidney disease. Hypernatremia (increased sodium levels) is not typically associated with chronic kidney disease. Low potassium and low magnesium are possible electrolyte imbalances in chronic kidney disease, but they are not as directly related to the impaired activation of vitamin D as hypocalcemia.

2. A nurse is preparing to administer lactated Ringer's (LR) 1,000 mL IV to infuse over 8 hr. The drop factor of the manual IV tubing is 10 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min?

• A. 19 gtt/min
• B. 20 gtt/min
• C. 21 gtt/min
• D. 22 gtt/min

Correct answer: C

Rationale: Calculation: 1000 mL / 480 minutes × 10 gtt/mL = 20.83, rounded to 21 gtt/min. This ensures proper IV fluid administration over the prescribed time. Choice C is the correct answer as it reflects the accurate calculation based on the given parameters. Choice A is incorrect because it does not accurately calculate the infusion rate. Choice B is incorrect as it does not consider the precise calculation required. Choice D is incorrect as it deviates from the correct calculation.

3. A client diagnosed with pneumonia is receiving oxygen therapy at 4 L/min via nasal cannula. Which of the following interventions is most important?

• A. Encourage fluid intake.
• B. Monitor oxygen saturation levels.
• C. Change the oxygen tubing daily.
• D. Assist with frequent position changes.

Correct answer: B

Rationale: Monitoring oxygen saturation levels is the most important intervention in this scenario. It ensures that the client is receiving adequate oxygenation, which is crucial for a client with pneumonia. By monitoring saturation levels, the nurse can promptly identify any oxygenation issues and adjust the oxygen delivery if necessary. Encouraging fluid intake, changing oxygen tubing daily, and assisting with frequent position changes are also important aspects of care for a client with pneumonia, but they are not as critical as monitoring oxygen saturation levels in ensuring immediate respiratory support.

4. A nurse is reviewing a client's medical record and notes that the client is taking tamoxifen. The nurse should identify that tamoxifen is used to treat which of the following conditions?

• A. Non-Hodgkin's lymphoma
• B. Endometriosis
• C. Breast cancer
• D. Polycystic ovary syndrome

Correct answer: C

Rationale: Tamoxifen is an anti-estrogen medication primarily used to treat hormone receptor-positive breast cancer. It works by blocking estrogen receptors in breast tissue, slowing the growth of tumors that require estrogen to grow. Choice A, Non-Hodgkin's lymphoma, is incorrect because tamoxifen is not indicated for its treatment. Choice B, Endometriosis, is incorrect as tamoxifen is not used for this condition. Choice D, Polycystic ovary syndrome, is also incorrect since tamoxifen is not a treatment for this syndrome.

5. A nurse is caring for a client with a new prescription for metoprolol. Which of the following should the nurse monitor?

• A. Blood pressure
• B. Liver function
• C. Serum potassium levels
• D. Blood glucose

Correct answer: A

Rationale: Corrected Rationale: Metoprolol is a beta-blocker commonly used to treat conditions like hypertension and angina. As a beta-blocker, it primarily affects the cardiovascular system by reducing heart rate and blood pressure. Therefore, the nurse should monitor the client's blood pressure regularly to assess the drug's effectiveness and ensure that it is within the therapeutic range. Monitoring liver function, serum potassium levels, or blood glucose is not typically required for clients taking metoprolol, as its primary impact is on the heart and blood vessels, making choice A the most appropriate monitoring parameter.
