Question 1 of 5

Which information should the nurse include in the teaching plan for the mother of a child diagnosed with cystic fibrosis (CF)? Select all that apply.

Correct Answer: A,B,D,E

Rationale: Postural drainage (1) helps clear mucus in CF. Modifying activities for physiotherapy (2) ensures adherence. Recognizing infection signs (4) and avoiding respiratory infections (5) prevent exacerbations. One liter of fluid (3) is insufficient for children; fluid needs vary by age and size.

Question 2 of 5

The client is suspected of having a pulmonary embolus. Which diagnostic test suggests the presence of a pulmonary embolus and requires further investigation?

A. Plasma D-dimer test. B. Arterial blood gases. C. Chest x-ray (CXR). D. Magnetic resonance imaging (MRI).

Correct Answer: A

Rationale: Elevated D-dimer (
A) suggests clotting, warranting further PE investigation (e.g., CT). ABGs (
B) show hypoxia, CXR (
C) is nonspecific, and MRI (
D) is not standard.

Question 3 of 5

Which arterial blood gas (ABG) results support the diagnosis of acute respiratory distress syndrome (ARDS) after the client has received O2 at 10 LPM?

A. pH 7.38, Pao2 94, Paco2 44, Hco3 24. B. pH 7.46, Pao2 82, Paco2 34, Hco3 22. C. pH 7.48, Pao2 59, Paco2 30, Hco3 26. D. pH 7.33, Pao2 94, Paco2 44, Hco3 20.

Correct Answer: C

Rationale: ARDS is characterized by severe hypoxemia despite high oxygen delivery. Pao2 59 (
C) despite 10 LPM oxygen indicates refractory hypoxia, a hallmark of ARDS. Normal Pao2 (94 in A and
D) contradicts ARDS. Pao2 82 (
B) is low but not as severe as 59, making C the best indicator of ARDS.

Question 4 of 5

Where on the client should the nurse position the sensor of the pulse oximeter to obtain an accurate measurement?

A. Apply it to the client's finger. B. Apply it to the client's palm. C. Clip it to the client's earlobe. D. Wrap it around the client's leg.

Correct Answer: A

Rationale: The finger is the most common and reliable site for pulse oximetry, providing accurate oxygenation readings.

Question 5 of 5

The HCP has recommended a total laryngectomy for a male client diagnosed with cancer of the larynx but the client refuses. Which intervention by the nurse illustrates the ethical principle of nonmalfeasance?

A. The nurse listens to the client explain why he is refusing surgery. B. The nurse and significant other insist that the client have the surgery. C. The nurse refers the client to a counselor for help with the decision. D. The nurse asks a cancer survivor to come and discuss the surgery with the client.

Correct Answer: A

Rationale: Listening to the client’s reasons (
A) respects autonomy and avoids harm (nonmalfeasance). Insisting (
B), counseling (
C), and survivor talks (
D) may pressure or influence unduly.
