Nursing Elites

1. A client who is receiving mechanical ventilation and has an ideal weight of 60 kg should have the tidal volume set at which of the following?

• A. 300 mL
• B. 480 mL
• C. 800 mL
• D. 950 mL

Correct answer: B

Rationale: Tidal volume is the amount of air delivered with each breath during mechanical ventilation. A common formula used to calculate tidal volume is 6-8 mL/kg of ideal body weight. For a client with an ideal weight of 60 kg, the expected tidal volume would be 60 kg x 6-8 mL/kg = 360-480 mL. Therefore, the most appropriate choice is 480 mL (Option B), which falls within the expected range based on the client's weight.

2. A client tests positive for alpha1-antitrypsin (AAT) deficiency and asks the nurse, What does this mean? How should the nurse respond?

• A. Your children may be at high risk for developing chronic obstructive pulmonary disease.
• B. I will arrange for a genetic counselor to discuss your condition.
• C. Your risk for chronic obstructive pulmonary disease is higher, particularly if you smoke.
• D. This is a recessive gene that should not affect your health.

Correct answer: C

Rationale: Alpha1-antitrypsin (AAT) deficiency is associated with a higher risk of chronic obstructive pulmonary disease (COPD), especially if the individual smokes. This condition is caused by a recessive gene. Individuals with one allele typically produce enough AAT to prevent COPD unless they smoke. However, those with two alleles are at high risk for COPD even without exposure to smoke or other irritants. Being a carrier of AAT deficiency does not guarantee that one's children will develop the disease; it depends on the AAT levels of the partner. While involving a genetic counselor may be beneficial in the long run, the immediate concern of the client's question should be addressed first.

3. A client is hospitalized with a second episode of pulmonary embolism (PE). Recent genetic testing reveals the client has an alteration in the gene CYP2C19. What action by the nurse is best?

• A. Instruct the client to eliminate all vitamin K from the diet.
• B. Prepare preoperative teaching for an inferior vena cava (IVC) filter.
• C. Refer the client to a chronic illness support group.
• D. Teach the client to use a soft-bristled toothbrush.

Correct answer: B

Rationale: Clients with an alteration in the CYP2C19 gene do not metabolize warfarin (Coumadin) well, leading to higher blood levels and more side effects. As this client is a poor candidate for warfarin therapy, the prescriber will most likely recommend the implantation of an inferior vena cava (IVC) filter. This device helps prevent blood clots from reaching the lungs, reducing the risk of pulmonary embolism.

4. A nurse assesses a client who has a history of heart failure. Which question should the nurse ask to assess the extent of the client's heart failure?

• A. Do you have trouble breathing or chest pain?
• B. Are you able to walk upstairs without fatigue?
• C. Do you awake with breathlessness during the night?
• D. Do you have new-onset heaviness in your legs?

Correct answer: B

Rationale: Clients with a history of heart failure generally have negative findings, such as shortness of breath. The nurse needs to determine whether the client's activity is the same or worse, or whether the client identifies a decrease in activity level. Trouble breathing, chest pain, breathlessness at night & peripheral edema are symptoms of heart failure, but do not provide data that can determine the extent of the client's heart failure.

5. A client with acute respiratory failure (ARF) is being cared for by a nurse. The nurse should monitor the client for which of the following manifestations of this condition?

• A. Severe dyspnea
• B. Nausea
• C. Decreased level of consciousness
• D. Headache

Correct answer: B

Rationale: In acute respiratory failure, the body is not getting enough oxygen, leading to hypoxia. Symptoms of hypoxia include severe dyspnea (A), decreased level of consciousness (C), and headache (D) due to inadequate oxygen supply to the brain. Nausea (B) is not a typical manifestation of acute respiratory failure and is not directly related to the lack of oxygen in the body. Therefore, the nurse should not monitor the client for nausea as a direct consequence of ARF.
