Nursing Elites

1. A client in the ICU has been intubated and placed on a ventilator. The physician orders synchronous intermittent mandatory ventilation (SIMV). Which statement best describes the work of this mode of ventilation?

• A. The ventilator delivers a set rate and tidal volume regardless of whether the client is attempting to breathe
• B. The ventilator coordinates delivered breaths with the client's respiratory efforts
• C. The ventilator provides a supplemental breath for every third breath of the client
• D. The ventilator provides breaths during the expiratory phase of the client's respirations

Correct answer: B

Rationale: Synchronous intermittent mandatory ventilation (SIMV) is a ventilation mode that coordinates delivered breaths with the client's own respiratory efforts. This mode allows the client to initiate breaths, with the ventilator providing preset breaths at a controlled rate and volume. Option A is incorrect because in SIMV, the ventilator syncs with the client's respiratory efforts. Option C is incorrect as it does not accurately depict the way SIMV works. Option D is also incorrect as SIMV does not specifically provide breaths during the expiratory phase of the client's respirations. Therefore, the correct answer is B, where the ventilator coordinates breath delivery with the client's breathing efforts.

2. Claudication is a well-known effect of peripheral vascular disease. Which of the following facts about claudication is correct? Select the one that doesn't apply:

• A. It results when oxygen demand is greater than oxygen supply.
• B. It is characterized by pain that often occurs during rest.
• C. It is a result of tissue hypoxia.
• D. It is characterized by cramping and weakness.

Correct answer: D

Rationale: Claudication is a symptom of peripheral vascular disease where there is an inadequate supply of oxygen to the muscles due to reduced blood flow. This mismatch between oxygen demand and supply leads to tissue hypoxia, resulting in cramping, weakness, and discomfort. Option D correctly states that claudication is characterized by cramping and weakness, making it the correct answer. Options A, B, and C are incorrect. Claudication occurs when oxygen demand exceeds supply, not the other way around as stated in Option A. Pain in claudication typically occurs with activity, not at rest as mentioned in Option B. While tissue hypoxia is a consequence of claudication, it is not the primary cause, making Option C incorrect.

3. A 30-year-old man is being admitted to the hospital for elective knee surgery. Which assessment finding is most important to report to the healthcare provider?

• A. Tympany on percussion of the abdomen
• B. Liver edge 3 cm below the costal margin
• C. Bowel sounds of 20/minute in each quadrant
• D. Aortic pulsations visible in the epigastric area

Correct answer: B

Rationale: The correct answer is 'Liver edge 3 cm below the costal margin.' Normally, the lower border of the liver is not palpable below the ribs, so this finding suggests hepatomegaly, which could indicate an underlying health issue. Tympany on percussion of the abdomen, bowel sounds of 20/minute in each quadrant, and aortic pulsations visible in the epigastric area are all within normal limits for a physical assessment and do not require immediate reporting to the healthcare provider.

4. A patient with Meningitis is being treated with Vancomycin intravenously 3 times per day. The nurse notes that the urine output during the last 8 hours was 200mL. What is the nurse's priority action?

• A. Check the patient's last BUN levels
• B. Ask the patient to increase their fluid intake
• C. Ask the physician to order a diuretic
• D. Notify the physician of this finding

Correct answer: D

Rationale: Vancomycin is a nephrotoxic drug and can cause impaired renal perfusion, which would lead to decreased urine output. This is a serious adverse effect that should be promptly reported to the physician. Checking the patient's last BUN levels (Choice A) may provide additional information but does not address the urgency of the situation. Asking the patient to increase fluid intake (Choice B) may not be appropriate if the cause is related to Vancomycin toxicity. Ordering a diuretic (Choice C) without physician evaluation can exacerbate the issue, making notifying the physician (Choice D) the most critical action to take.

5. When teaching the client with tuberculosis about follow-up home care, the nurse should emphasize that a laboratory appointment for which of the following lab tests is critical?

• A. Liver function
• B. Kidney function
• C. Blood sugar
• D. Cardiac enzymes

Correct answer: A

Rationale: The nurse should emphasize the importance of monitoring liver function tests in clients taking INH due to the risk of hepatocellular injury and hepatitis associated with this medication. Regular assessment of liver enzymes can help detect liver damage early. Monitoring kidney function, blood sugar levels, or cardiac enzymes is not specifically required for clients taking INH and tuberculosis treatment.
