Nursing Elites

1. A client with asthma has low-pitched wheezes present on the final half of exhalation. One hour later the client has high-pitched wheezes extending throughout exhalation. This change in assessment indicates to the nurse that the client

• A. Has increased airway obstruction
• B. Has improved airway obstruction
• C. Needs to be suctioned
• D. Exhibits hyperventilation

Correct answer: B

Rationale: The higher pitched a sound is, the more narrow the airway. Therefore, the obstruction has increased or worsened. With no evidence of secretions, there is no support to indicate the need for suctioning. Wheezes changing from low-pitched to high-pitched and extending throughout exhalation suggest a progression in airway constriction, indicating an increase in airway obstruction. Option B is incorrect because the change in wheezes from low to high pitch does not suggest an improvement in airway obstruction. Option C is incorrect as there is no indication of secretions requiring suctioning. Option D is incorrect as hyperventilation is not typically associated with the described change in wheezes.

2. Following assessment of a patient with pneumonia, the nurse identifies a nursing diagnosis of ineffective airway clearance. Which assessment data best supports this diagnosis?

• A. Weak, nonproductive cough effort
• B. Large amounts of greenish sputum
• C. Respiratory rate of 28 breaths/minute
• D. Resting pulse oximetry (SpO2) of 85%

Correct answer: A

Rationale: The correct answer is 'Weak, nonproductive cough effort.' A weak, nonproductive cough indicates that the patient is unable to clear the airway effectively, supporting the nursing diagnosis of ineffective airway clearance. In pneumonia, secretions can obstruct the airway, leading to ineffective clearance. Choices B, C, and D do not directly reflect ineffective airway clearance. Large amounts of greenish sputum (Choice B) may suggest infection or inflammation but do not specifically indicate ineffective airway clearance. The respiratory rate of 28 breaths/minute (Choice C) and a resting pulse oximetry (SpO2) of 85% (Choice D) are more indicative of impaired gas exchange or respiratory distress rather than ineffective airway clearance.

3. Which response by the nurse best explains the purpose of ranitidine (Zantac) for a patient admitted with bleeding esophageal varices?

• A. The medication will reduce the risk of aspiration.
• B. The medication will inhibit the development of gastric ulcers.
• C. The medication will prevent irritation of the enlarged veins.
• D. The medication will decrease nausea and improve appetite.

Correct answer: C

Rationale: The correct answer is: 'The medication will prevent irritation of the enlarged veins.' Esophageal varices are dilated submucosal veins. The therapeutic action of H2-receptor blockers in patients with esophageal varices is to prevent irritation and bleeding from the varices caused by reflux of acidic gastric contents. While ranitidine can decrease the risk of peptic ulcers, reduce nausea, and help prevent aspiration pneumonia, the primary purpose of H2-receptor blockade in this patient is to prevent irritation and bleeding from the varices, not the other listed effects.

4. A patient asks the nurse why they must have a heparin injection. What is the nurse's best response?

• A. Heparin will dissolve clots that you have.
• B. Heparin will reduce the platelets that make your blood clot.
• C. Heparin will work better than warfarin.
• D. Heparin will prevent new clots from developing.

Correct answer: D

Rationale: The correct answer is D: 'Heparin will prevent new clots from developing.' Heparin is an anticoagulant medication that helps prevent the formation of new blood clots. It does not dissolve existing clots (choice A), reduce platelets (choice B), or necessarily work 'better' than warfarin (choice C) but rather functions differently. The primary action of heparin is to prevent the development of new clots, especially in conditions where clot formation is a concern.

5. A 1-year-old child is diagnosed with intussusception, and the mother of the child asks the student nurse to describe the disorder. Which statement by the student nurse indicates correct understanding of this disorder?

• A. It is an acute bowel obstruction.
• B. It is a condition that causes an acute inflammatory process in the bowel.
• C. It is a condition in which a distal segment of the bowel prolapses into a proximal segment of the bowel.
• D. It is a condition in which a proximal segment of the bowel prolapses into a distal segment of the bowel.

Correct answer: D

Rationale: Intussusception is a condition in which a proximal segment of the bowel telescopes or prolapses into a distal segment of the bowel. This leads to bowel obstruction and potential ischemia. It is not an acute bowel obstruction, as the obstruction is caused by the telescoping of bowel segments rather than a blockage in the bowel lumen. Intussusception is not primarily an inflammatory process; instead, it is a mechanical issue involving bowel invagination. Choice A is incorrect as it does not accurately describe the pathophysiology of intussusception. Choice C is incorrect because it presents the opposite scenario of what happens in intussusception.
