Nursing Elites

1. A teenager presents to the emergency department with palpitations after vaping at a party. The client is anxious, fearful, and hyperventilating. Which acid-base imbalance does the nurse anticipate the client developing?

• A. Metabolic alkalosis
• B. Respiratory alkalosis
• C. Respiratory acidosis
• D. Metabolic acidosis

Correct answer: B

Rationale: The correct answer is B: Respiratory alkalosis. Hyperventilation from anxiety or fear causes an excessive loss of CO2, leading to respiratory alkalosis. This shift in pH results from the rapid, shallow breathing that reduces the level of carbon dioxide in the blood. Respiratory acidosis would occur in cases of poor ventilation or CO2 retention, while metabolic acidosis/alkalosis relates to disturbances in bicarbonate, not breathing patterns. Therefore, in this case, the client's hyperventilation due to anxiety would likely result in respiratory alkalosis, making option B the correct choice.

2. A client with chronic obstructive pulmonary disease (COPD) is being discharged home. What should the nurse include in the discharge teaching?

• A. Limit fluid intake to prevent lung congestion
• B. Avoid all physical activity to conserve energy
• C. Perform pursed-lip breathing during activities
• D. Increase oxygen flow rate if shortness of breath occurs

Correct answer: C

Rationale: The correct answer is C. Pursed-lip breathing helps control breathing and improves oxygen exchange in clients with COPD. It can ease shortness of breath during activities and should be included in discharge teaching to manage symptoms. Option A is incorrect as adequate fluid intake is important for thinning mucus in COPD. Option B is wrong as physical activity, as tolerated, is beneficial for COPD patients. Option D is also incorrect because changing oxygen flow rate without healthcare provider guidance can be dangerous.

3. What pathophysiological events occur sequentially in the development of atherosclerosis?

• A. Foam cells release growth factors.
• B. Smooth muscle grows over fatty streaks creating fibrous plaques.
• C. Macrophages consume low-density lipoprotein (LDL) and create foam cells.
• D. Arterial endothelium injury causes inflammation.

Correct answer: D

Rationale: The correct sequence of pathophysiological events in the development of atherosclerosis starts with arterial endothelium injury causing inflammation. This inflammation triggers the formation of foam cells by macrophages consuming low-density lipoprotein (LDL). Subsequently, smooth muscle grows over fatty streaks, creating fibrous plaques. Therefore, option D is the correct answer. Choices A, B, and C are incorrect because they do not reflect the accurate chronological order of events in the pathogenesis of atherosclerosis.

4. A client reports dizziness when standing up quickly. What advice should the nurse give?

• A. Encourage the client to drink more fluids.
• B. Change positions slowly to prevent dizziness.
• C. Report the symptom to the healthcare provider immediately.
• D. Limit physical activity to avoid triggering dizziness.

Correct answer: B

Rationale: The correct advice for a client experiencing dizziness when standing up quickly is to change positions slowly to prevent dizziness. This symptom is suggestive of postural hypotension, where a sudden change in position can lead to a drop in blood pressure, causing dizziness. Encouraging the client to drink more fluids (Choice A) may be beneficial for other conditions but is not directly related to the prevention of dizziness in this case. Reporting the symptom to the healthcare provider immediately (Choice C) is important if the dizziness is persistent or severe, but the immediate action to prevent it is to change positions slowly. Limiting physical activity (Choice D) may not necessarily address the underlying cause of dizziness in this context.

5. A client who had a subtotal parathyroidectomy two days ago is now preparing for discharge. Which assessment finding requires immediate provider notification?

• A. Afebrile with a normal pulse.
• B. No bowel movement since surgery.
• C. No appetite for breakfast.
• D. A positive Chvostek's sign.

Correct answer: D

Rationale: A positive Chvostek's sign suggests hypocalcemia, which is a post-parathyroidectomy complication and requires prompt treatment. The other options are less urgent: being afebrile with a normal pulse is expected, no bowel movement since surgery can be managed with interventions like early ambulation and stool softeners, and no appetite for breakfast is common postoperatively and can be addressed without immediate provider notification.
