A patient with right lower-lobe pneumonia has been treated with intravenous antibiotics for 3 days.Which assessment data obtained by the nurse indicates that the treatment is effective?

Decreased white blood cell count.

Increased chest pain and shortness of breath.

Adventitious breath sounds and increased cough.

Improved appetite and weight gain.

Answer and Explanation

The Correct Answer is A

Choice A rationale

A decreased white blood cell count indicates the body's response to infection is improving, showing the effectiveness of the antibiotics.

Choice B rationale

Increased chest pain and shortness of breath would suggest worsening of the condition, not improvement.

Choice C rationale

Adventitious breath sounds and increased cough are signs that pneumonia may be persisting or worsening.

Choice D rationale

Improved appetite and weight gain are positive signs but are not direct indicators of the effectiveness of antibiotic treatment.

Correct Answer is B

Explanation

Choice A rationale

Hypokalemia involves low potassium levels and is not treated with sodium polystyrene sulfonate. This drug is used to treat elevated potassium levels.

Choice B rationale

Hyperkalemia indicates high potassium levels in the blood. Sodium polystyrene sulfonate (Kayexalate) works by exchanging sodium ions for potassium ions in the intestines, thereby lowering blood potassium levels.

Choice C rationale

Hyponatremia, or low sodium levels, is not treated with sodium polystyrene sulfonate, which targets potassium removal.

Choice D rationale

Hypocalcemia refers to low calcium levels and is unrelated to the action of sodium polystyrene sulfonate, which addresses potassium imbalance.

A. Place the client in the supine position. B. Administer morphine intramuscularly. C. Administer nitroglycerin subcutaneously. D. Administer aspirin 325 orally. E. Apply oxygen via nasal cannula.

Correct Answer is ["D","E"]

Explanation

Choice D rationale

Administering aspirin 325 orally is important for clients with a myocardial infarction (MI). Aspirin helps to inhibit platelet aggregation, reducing the risk of further clot formation and improving blood flow to the heart. This can significantly decrease mortality and complications associated with MI.

Choice E rationale

Applying oxygen via nasal cannula helps to increase oxygen delivery to the heart and other vital organs during an MI. Ensuring adequate oxygenation can help reduce the extent of myocardial injury and support overall cardiac function during a critical period.

Choice A rationale

Placing the client in a supine position is not appropriate during an MI, as it can increase discomfort and the workload on the heart. Instead, the client should be positioned in a semi-Fowler’s or comfortable position to improve breathing and comfort.

Choice B rationale

Administering morphine intramuscularly is not recommended during an MI. Morphine can be used for pain relief but should be given intravenously to ensure rapid onset and better control over dosing. Intramuscular administration is less effective and can delay pain relief.

Choice C rationale

Administering nitroglycerin subcutaneously is not appropriate. Nitroglycerin is typically given sublingually or intravenously during an MI to provide rapid vasodilation and pain relief. Subcutaneous administration is not effective in this context. .
