1. 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.

2. A nurse is orienting a newly licensed nurse on performing a routine assessment of a client who is receiving mechanical ventilation via an endotracheal tube. Which of the following information should the nurse include in the teaching?

A. Apply a vest restraint if self-extubation is attempted.
B. Monitor ventilator settings every 8 hours.
C. Document tube placement in centimeters at the angle of the jaw.
D. Assess breath sounds every 1 to 2 hours.

Correct answer: D

Rationale: Assessing breath sounds every 1 to 2 hours is crucial in monitoring the client's respiratory status and identifying any potential complications promptly. Monitoring ventilator settings every 8 hours is important for overall ventilation management. Documenting the endotracheal tube placement accurately is essential to ensure proper positioning. Using a vest restraint if self-extubation is attempted is not a recommended intervention as it can lead to complications and should be avoided.

3. What is the appropriate needle size for insulin injection?

A. 18G, 1 ½” long
B. 22G, 1” long
C. 22G, 1 ½” long
D. 25G, 5/8” long

Correct answer: D

Rationale: The appropriate needle size for insulin injection is 25G, 5/8” long. This size allows for accurate and comfortable insulin administration in subcutaneous tissue.

4. 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.

5. The nurse observes that Mr. Adams begins to have increased difficulty breathing. She elevates the head of the bed to the high Fowler position, which decreases his respiratory distress. The nurse documents this breathing as:

A. Tachypnea
B. Eupnea
C. Orthopnea
D. Hyperventilation

Correct answer: C

Rationale: Orthopnea is a condition where a person experiences difficulty breathing when lying flat but finds relief when sitting up or standing. Elevating the head of the bed to the high Fowler position helps alleviate this symptom. Tachypnea refers to rapid breathing, eupnea is normal breathing, and hyperventilation is breathing excessively fast or deep.
