Correct Answer: C

Rationale: In a client with pneumonia, crackles in the lung bases can indicate fluid accumulation, worsening of the condition, or development of complications such as pulmonary edema. This finding should be reported to the provider promptly for further evaluation and management. Choices A, B, and D are common in clients with pneumonia and may not necessarily require immediate reporting unless accompanied by other concerning symptoms or vital sign abnormalities.

Correct Answer: A

Rationale: Providing education about the importance of medication adherence is crucial in managing hypertension. By educating the patient about the significance of taking their medication as prescribed, the healthcare provider can help improve compliance and control the patient's blood pressure. Referring the patient to a specialist (Choice B) may be necessary in some cases but addressing non-compliance should start with education. Exploring alternative treatments (Choice C) could be considered if the current medication is not suitable, but initial steps should focus on improving adherence. Reassessing the patient in 6 months (Choice D) may be too delayed if non-compliance is an issue that needs immediate attention.

Correct Answer: C

Rationale: A platelet count of 90,000/mm³ indicates thrombocytopenia, which increases the risk of bleeding and requires immediate intervention. Thrombocytopenia can lead to serious bleeding complications, so it is crucial to address this finding promptly. A low white blood cell count (choice A) may indicate neutropenia but is not as immediately life-threatening as severe thrombocytopenia. A hemoglobin level of 8 g/dL (choice B) would require intervention but is not as urgent as addressing a critically low platelet count. A serum potassium level of 3.5 mEq/L (choice D) is on the lower side of normal but does not pose an immediate risk to the client's safety compared to severe thrombocytopenia.

Correct Answer: A

Rationale: The correct answer is to administer epinephrine. Epinephrine is the first-line treatment for severe allergic reactions as it helps reverse the symptoms rapidly by constricting blood vessels, increasing heart rate, and opening airways. Antihistamines (Choice B) may help with mild allergic reactions but are not effective for severe cases. Corticosteroids (Choice C) are used to reduce inflammation and are typically not the first-line treatment for acute severe allergic reactions. Administering oxygen (Choice D) may be necessary to support breathing in severe cases, but epinephrine is the primary treatment to reverse the allergic reaction symptoms.

Correct Answer: A

Rationale: The correct answer is A: Hypokalemia. Furosemide, a loop diuretic, can lead to potassium loss in the body, resulting in hypokalemia. This electrolyte imbalance is commonly associated with furosemide use due to its mechanism of action in the kidneys. Hyponatremia (choice B) is not typically associated with furosemide. Hyperkalemia (choice C) and hypercalcemia (choice D) are not common electrolyte imbalances seen with furosemide use.
