A nurse is caring for a client who is receiving positive end-expiratory pressure (PEEP) via mechanical ventilation. The nurse should monitor the client for which of the following adverse effects of PEEP?

Hypoxemia

Tension pneumothorax.

Malignant hypertension

Atelectasis

Answer and Explanation

The Correct Answer is B

A. Hypoxemia is a condition of low oxygen levels in the blood. PEEP can actually improve oxygenation by preventing alveolar collapse and increasing functional residual capacity.

B. Tension pneumothorax is a life-threatening condition of air accumulation in the pleural space that causes increased intrathoracic pressure and compresses the lungs, heart, and great vessels. PEEP can increase the risk of tension pneumothorax by creating excessive positive pressure in the airways and alveoli.

C. Malignant hypertension is a severe form of high blood pressure that can cause organ damage and stroke. PEEP can cause a transient increase in blood pressure due to increased intrathoracic pressure, but it does not cause malignant hypertension.

D. Atelectasis is a condition of partial or complete lung collapse due to alveolar collapse or obstruction. PEEP can prevent or treat atelectasis by maintaining positive pressure in the airways and alveoli.

Correct Answer is A

Explanation

- A is correct because aPTT (activated partial thromboplastin time) measures the effectiveness of heparin therapy and guides dosage adjustments.

- B is incorrect because PT (prothrombin time) measures the effectiveness of warfarin therapy, not heparin.

- C is incorrect because INR (international normalized ratio) is a standardized version of PT that also monitors warfarin therapy, not heparin.

- D is incorrect because WBC count (white blood cell count) measures the body's immune response and has no relation to heparin therapy.

A. "Have you experienced muscle stiffness?" B. "Have you had any stomach pain or bloody stools?" C. "Have you experienced a dry cough?" D. "Have you noticed an increase in urine output?"

Correct Answer is B

Explanation

"Have you had any stomach pain or bloody stools?"

Rationale:

A. Muscle stiffness is not a common or serious adverse effect of ibuprofen. Ibuprofen is an antiinflammatory drug that can reduce pain and stiffness caused by arthritis.
B. Stomach pain or bloody stools are signs of gastrointestinal bleeding, which is a serious and potentially fatal adverse effect of ibuprofen. Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that can cause ulceration, perforation, and hemorrhage of the stomach or intestines . The nurse should ask the client about any gastrointestinal symptoms and advise them to avoid alcohol, smoking, and other NSAIDs while taking ibuprofen.
C. Dry cough is not a common or serious adverse effect of ibuprofen. Dry cough is more likely to be caused by angiotensin-converting enzyme (ACE) inhibitors, which are used to treat hypertension and heart failure.
D. Increase in urine output is not a common or serious adverse effect of ibuprofen. Ibuprofen can cause renal impairment, which can lead to decreased urine output, not increased urine output. The nurse should monitor the client's renal function tests and fluid balance while taking ibuprofen.
