Nursing Elites

1. The client with high blood pressure is being taught by the nurse to avoid adding salt during cooking. What effect does sodium have on blood pressure?

• A. It decreases the viscosity of blood
• B. It leads to increased fluid retention
• C. It causes vasoconstriction of the blood vessels
• D. It enhances the excretion of potassium

Correct answer: C

Rationale: The correct answer is C: 'It causes vasoconstriction of the blood vessels.' Sodium can lead to vasoconstriction, which narrows the blood vessels, increasing resistance to blood flow and subsequently raising blood pressure. Choices A, B, and D are incorrect. Sodium does not decrease blood viscosity, but it can lead to fluid retention, which increases blood volume and pressure. It does not enhance the excretion of potassium; instead, high sodium intake can lead to potassium excretion by the kidneys.

2. The wife is observed shaving her husband's beard with a safety razor. What should the nurse do?

• A. Advise the wife to shave against the hair growth
• B. Teach the wife to keep the skin loose to avoid cuts
• C. Encourage the wife to continue shaving her husband
• D. Demonstrate the correct procedure to the wife

Correct answer: C

Rationale: In this situation, the nurse should encourage the wife to continue shaving her husband. The rationale behind this is that the wife is already performing the task, so abrupt interference may lead to potential harm or emotional distress. It is crucial for the nurse to carefully observe the situation and assess for any safety concerns. While teaching proper techniques (Choice B) is important, it can be addressed later in a non-critical manner to prevent skin irritation and injury. Advising to shave against the hair growth (Choice A) may cause skin irritation and cuts. Although demonstrating the correct procedure (Choice D) may be helpful, it is essential to consider the current dynamics and respect the wife's autonomy in caring for her husband.

3. The nurse is preparing to administer a subcutaneous injection of heparin. What is the correct angle of insertion?

• A. 15 degrees
• B. 30 degrees
• C. 45 degrees
• D. 90 degrees

Correct answer: C

Rationale: The correct angle of insertion for a subcutaneous injection, such as heparin, is 45 degrees. This angle is appropriate as it helps to ensure proper delivery of the medication into the subcutaneous tissue. Option A (15 degrees) is too shallow for a subcutaneous injection and may result in the medication being deposited into the muscle. Option B (30 degrees) is also too shallow for subcutaneous injections. Option D (90 degrees) is used for intramuscular injections, not subcutaneous injections.

4. The nurse is with a client when the healthcare provider explains that the biopsy classifies the results as a T1N0M0 tumor. What response should the nurse provide first?

• A. The letters represent tumor size, node involvement, and metastasis in cancer staging.
• B. The letters stand for tumor size, node involvement, and metastasis.
• C. Let me explain the cancer staging to you.
• D. Would you like further clarification on the tumor staging?

Correct answer: B

Rationale: Choice B is the correct answer as it accurately explains that the letters T, N, and M in cancer staging represent tumor size, node involvement, and metastasis, respectively. Understanding this staging system helps the client comprehend the extent and severity of the disease. Choices A, C, and D are incorrect. Choice A has the correct information but is not the most precise response. Choice C is vague and does not directly address the client's need for clarification. Choice D offers further clarification without directly addressing the initial explanation provided by the healthcare provider.

5. While caring for a client who is being mechanically ventilated, the nurse responds to a high-pressure alarm on the ventilator. Which assessment finding warrants immediate intervention by the nurse?

• A. Endotracheal cuff pressure greater than 25 cm H2O.
• B. Decreased lung compliance during ventilation.
• C. Bilateral crackles with increased secretions.
• D. Restless client who is biting the endotracheal tube.

Correct answer: D

Rationale: A restless client biting the endotracheal tube can increase airway resistance, triggering the high-pressure alarm and indicating a need for immediate intervention. This behavior can lead to complications such as dislodgement of the tube or airway obstruction. Endotracheal cuff pressure greater than 25 cm H2O, decreased lung compliance, and bilateral crackles with increased secretions are important assessments but do not directly address the urgent need to intervene when a high-pressure alarm is triggered.
