A client receiving mechanical ventilation has a pH of 7.26, PaCO2 of 68 mm Hg, and a PaO2 of 92 mm Hg. Which intervention should the nurse implement?

Decrease expiratory flow time.

Decrease expiratory pressure.

Increase rate of ventilation.

Increase ventilator tidal volume.

Answer and Explanation

The Correct Answer is B

Choice A rationale:

Decreasing expiratory flow time is not the appropriate intervention in this case. The client's pH and PaCO2 levels suggest respiratory acidosis, which indicates inadequate ventilation. Increasing expiratory flow time might exacerbate the acidosis by reducing ventilation.

Choice C rationale:

Increasing the rate of ventilation (respiratory rate) is a potential intervention to improve the client's acid-base balance. However, it should be done cautiously and under medical supervision to avoid respiratory alkalosis. It is not the first-line intervention in this scenario.

Choice D rationale:

Increasing the ventilator tidal volume may help improve ventilation, but it should also be done under medical guidance to prevent barotrauma. It is not the initial intervention to address the client's respiratory acidosis.

Correct Answer is ["A","B","D"]

Explanation

Choice A rationale:

An elevated serum creatinine level can indicate kidney dysfunction or damage, which can be a possible adverse effect of amoxicillin-clavulanate. The kidneys are responsible for excreting the medication, and elevated creatinine levels suggest impaired renal function.

Choice B rationale:

An elevated serum alanine aminotransferase (ALT) level is indicative of liver dysfunction or damage. Amoxicillin-clavulanate can sometimes cause hepatotoxicity as a side effect, and elevated ALT levels may suggest this adverse effect.

Choice D rationale:

An elevated white blood cell count (leukocytosis) can be a possible adverse effect of amoxicillin-clavulanate, indicating an increase in the body's immune response. This could be due to an allergic reaction or other adverse reactions to the medication.

Choice C rationale:

An elevated serum potassium level is not typically associated with amoxicillin-clavulanate use. This finding is more likely related to other factors such as kidney dysfunction or certain medications like potassium-sparing diuretics.

Choice E rationale:

An elevated platelet count is not typically associated with amoxicillin-clavulanate use. This finding is more likely related to other factors, such as a bone marrow disorder or inflammation.

A. Tachycardia B. Hyperglycemia C. Bronchospasm D. Hyperkalemia.

Correct Answer is C

Explanation

The correct answer is: C. Bronchospasm.

Metoprolol is a selective beta-1 blocker, primarily affecting the heart, but it can still have some impact on beta-2 receptors in the lungs. In clients with respiratory conditions like asthma or COPD, beta-blockers can trigger bronchospasm, leading to breathing difficulties.

Here's why the other options are less likely to be adverse effects of metoprolol:

A. Tachycardia: Metoprolol actually lowers heart rate, so tachycardia is not a typical adverse effect. Instead, bradycardia (slow heart rate) is more common.
B. Hyperglycemia: Beta-blockers can sometimes mask symptoms of hypoglycemia, but they don’t directly cause high blood sugar.
D. Hyperkalemia: Metoprolol doesn’t significantly affect potassium levels, so hyperkalemia is not a common concern.

Since metoprolol is frequently used in hypertension management, nurses must monitor clients for bradycardia, hypotension, and signs of bronchospasm, especially in individuals with respiratory disorders.
