1. When planning care for a client on mechanical ventilation, which mode of ventilation that increases the effort of the client's respiratory muscles should NOT be included in the plan of care?

• A. Assist-control
• B. Synchronized intermittent mandatory ventilation
• C. Continuous positive airway pressure
• D. Pressure support ventilation

Correct answer: A

Rationale: Assist-control ventilation mode delivers a preset tidal volume at a set rate; however, it may not be suitable for clients who need to maintain some level of respiratory muscle activity. This mode provides full support for each breath, potentially leading to decreased respiratory muscle strength over time. Therefore, it is important to avoid using assist-control mode for clients who require increased effort of respiratory muscles to prevent muscle atrophy and promote optimal respiratory function.

2. When administering digoxin 0.125 mg PO to an adult client, for which of the following findings should the nurse report to the provider?

• A. Potassium level 4.2 mEq/L.
• B. Apical pulse 58/min
• C. Digoxin level 1 ng/mL
• D. Constipation for 2 days

Correct answer: C

Rationale: Monitoring the digoxin level is crucial as it helps determine the drug's effectiveness and potential toxicity. A digoxin level of 1 ng/mL is within the therapeutic range. However, levels above this range can lead to toxicity, causing adverse effects like nausea, vomiting, visual disturbances, and dysrhythmias. Therefore, the nurse should report a digoxin level of 1 ng/mL to the provider for further evaluation and potential dose adjustment.

3. A client with active tuberculosis is prescribed isoniazid, rifampin, pyrazinamide, and ethambutol. Which statement by the client indicates an understanding of the teaching?

• A. I can substitute one medication for another if I run out because they all fight infection.
• B. I will wash my hands each time I cough.
• C. I am glad I don't have to have any more sputum specimens.
• D. I don't need to worry about where I go once I start taking my medications.

Correct answer: B

Rationale: The correct statement indicating understanding of tuberculosis medication regimen is 'I will wash my hands each time I cough.' This statement shows knowledge of infection control practices to prevent the spread of tuberculosis. Washing hands after coughing helps in reducing the transmission of the disease to others. The other options are incorrect. Option A is incorrect as each medication in the regimen has a specific role, and substituting one for another can compromise the effectiveness of treatment. Option C is incorrect as obtaining sputum specimens is essential for monitoring treatment response. Option D is incorrect as the client should still adhere to infection control measures and avoid exposing others to tuberculosis.

4. A 38-year-old patient’s vital signs at 8 a.m. are axillary temperature 99.6°F (37.6°C); pulse rate 88; respiratory rate 30. Which findings should be reported?

• A. Respiratory rate only
• B. Temperature only
• C. Pulse rate and temperature
• D. Temperature and respiratory rate

Correct answer: D

Rationale: Both an elevated temperature and an increased respiratory rate are abnormal vital signs that could indicate an underlying health issue. Reporting both of these findings is crucial to ensure appropriate evaluation and intervention if needed.

5. Which chamber of the heart receives oxygenated blood from the lungs?

• A. Left atrium
• B. Right atrium
• C. Left ventricle
• D. Right ventricle

Correct answer: A

Rationale: The correct answer is A, the left atrium. The left atrium receives oxygenated blood from the lungs through the pulmonary veins. This blood is then pumped into the left ventricle before being circulated throughout the body. The right atrium, represented by choice B, actually receives deoxygenated blood from the body through the vena cava. Choices C and D, the left ventricle and right ventricle respectively, are chambers involved in pumping blood out of the heart to the body and lungs, rather than receiving blood from the lungs.
