Question 1 of 5

The nurse is admitting a client with a diagnosis of rule-out cancer of the larynx. Which information should the nurse teach?

Correct Answer: C

Rationale: Laryngoscopy with biopsy (
C) diagnoses laryngeal cancer, requiring client education. Gargling (
A), voice exercises (
B), and self-examination (
D) are not diagnostic.

Question 2 of 5

You are providing teaching to a patient with chronic COPD on how to perform diaphragmatic breathing. This technique helps do the following:

A. Increase the breathing rate to prevent hypoxemia B. Decrease the use of the abdominal muscles C. Encourages the use of accessory muscles to help with breathing D. Strengthen the diaphragm

Correct Answer: D

Rationale: Diaphragmatic breathing strengthens the diaphragm , improving breathing efficiency in COPD. It doesn't increase breathing rate , decrease abdominal muscle use , or encourage accessory muscle use .

Question 3 of 5

A patient taking Isoniazid (INH) should be monitored for what deficiency?

A. Vitamin C B. Calcium C. Vitamin B6 D. Potassium

Correct Answer: C

Rationale: This medication can lead to low Vitamin B6 levels. Most patients will take a supplement of B6 while taking this medication.

Question 4 of 5

The nurse suspects the client admitted with a near-drowning is developing acute respiratory distress syndrome (ARDS). Which data support the nurse's suspicion?

A. The client's arterial blood gases are within normal limits. B. The client appears anxious, has dyspnea, and is tachypneic. C. The client has intercostal retractions and is using accessory muscles. D. The client has bilateral lung sounds with crackles and rhonchi.

Correct Answer: C

Rationale: Intercostal retractions and accessory muscle use (
C) indicate severe respiratory distress, consistent with ARDS due to increased work of breathing from reduced lung compliance. Normal ABGs (
A) contradict ARDS, which involves hypoxia. Anxiety, dyspnea, and tachypnea (
B) are non-specific. Crackles and rhonchi (
D) may occur but are less specific than physical signs of distress.

Question 5 of 5

The nurse instructs the client's spouse to empty and thoroughly clean the vaporizer after each use. Which rationale provides the basis for the nurse's instruction?

A. There is a potential for injury if the vaporizer is accidentally knocked off a nightstand. B. When the vaporizer is not cleaned, there is the growth of environmental pathogens. C. The vaporizer can collect dust, which could affect the client's breathing. D. Water evaporation causes calcium deposits that will obstruct the vaporizer.

Correct Answer: B

Rationale: A cool-mist vaporizer can harbor pathogens like bacteria and mold if not cleaned properly, potentially worsening respiratory symptoms.
