Question 1 of 5

After a lobectomy for lung cancer, the nurse instructs the client to perform deep-breathing exercises to:

Correct Answer: D

Rationale: Deep-breathing exercises expand alveoli, increasing lung surface area for ventilation post-lobectomy.

Question 2 of 5

Which of the following statements indicates that the client with a peptic ulcer understands the dietary modifications he needs to follow at home?

Correct Answer: D

Rationale: Avoiding alcohol and caffeine is critical for peptic ulcer management, as these substances can exacerbate ulcer symptoms and delay healing.

Question 3 of 5

The nurse notices drops of a liquid on the hallway floor of a health care facility. The nurse should do which of the following first?

Correct Answer: C

Rationale: Posting 'wet floor' signs first ensures immediate safety by alerting others to the hazard, preventing slips.
Then, the nurse can proceed with cleanup or notify appropriate personnel.

Question 4 of 5

The nurse cares for a client who is pale and frequently reports fatigue, weakness, and dizziness. Which serum laboratory test result is the nurse's priority for planning care?

Correct Answer: D

Rationale: The client's hemoglobin level and sodium level are low; however, the nurse uses the hemoglobin results to plan care because the client's clinical indicators are consistent with anemia. The client is pale because the serum hemoglobin is low; thus, the client's tissues are perfused with blood that has a low oxygen-carrying capacity. The client is weak and dizzy because the blood does not carry enough oxygen to meet tissue oxygen demands. The normal sodium level is 135 to 145 mEq/L (135 to 145 mmol/L). Although a client who is hyponatremic can also feel weak and dizzy, a hyponatremic client is unlikely to be pale. The hematocrit and the potassium levels are within normal limits.

Question 5 of 5

The nurse is assessing a newborn 24 hours after birth. Which finding requires immediate reporting?

Correct Answer: D

Rationale: Yellowing of the skin within 24 hours suggests pathological jaundice, requiring immediate evaluation to prevent complications like kernicterus.
