What is the initial intervention for a patient experiencing an allergic reaction?

Correct Answer: A

Rationale: The correct answer is to administer antihistamines as the initial intervention for a patient experiencing an allergic reaction. Antihistamines work to block the effects of histamine, a substance released during an allergic reaction, helping to relieve symptoms such as itching, swelling, and hives. Corticosteroids (Choice B) are sometimes used in severe cases to reduce inflammation, but they are not the first-line treatment for an allergic reaction. Administering oxygen (Choice C) may be necessary if the patient is having difficulty breathing, but it is not the first intervention. IV fluids (Choice D) are typically given for conditions like dehydration or shock, not as the primary intervention for an allergic reaction.

Correct Answer: A

Rationale: Monitoring daily weight is the most accurate way to assess fluid overload in patients with heart failure. In heart failure, the body retains excess fluid, leading to weight gain. Monitoring daily weight allows healthcare professionals to track fluid retention accurately. Checking for edema (Choice B) is a valuable assessment technique, but it may not be as sensitive as monitoring daily weight. Monitoring blood pressure (Choice C) is essential in managing heart failure, but it is not the most accurate way to assess fluid overload. Checking oxygen saturation (Choice D) is important to assess respiratory status but is not directly related to fluid overload in heart failure.

Correct Answer: A

Rationale: The correct answer is A: Administer oxygen. Administering oxygen is the priority intervention for a patient with a suspected pulmonary embolism to improve oxygenation levels. In pulmonary embolism, there is a blockage in one of the pulmonary arteries, leading to decreased oxygen exchange. Administering oxygen helps increase oxygen saturation levels. Anticoagulants (Choice B) are essential in the treatment of pulmonary embolism but are not the initial priority intervention. Surgery (Choice C) is not typically the first-line treatment for pulmonary embolism. Monitoring oxygen saturation (Choice D) is important but administering oxygen takes precedence as the immediate action to address hypoxemia.

Correct Answer: A

Rationale: The correct answer is A: Hypokalemia. Furosemide is a loop diuretic that can lead to potassium loss, resulting in hypokalemia. This electrolyte imbalance necessitates close monitoring to prevent complications such as cardiac arrhythmias. Choices B, C, and D are incorrect. Hypercalcemia is not a common side effect of furosemide. Hyponatremia is more commonly associated with other medications like thiazide diuretics. Hyperkalemia is the opposite electrolyte imbalance and is not typically seen with furosemide use.

Correct Answer: A

Rationale: The correct answer is A: Educate the patient on the importance of medication. Providing education to the patient is crucial in promoting understanding of the condition and the necessity of medication. By enhancing the patient's knowledge, healthcare providers can empower them to make informed decisions regarding their health. Choice B, respecting the patient's decision, may not be appropriate in this scenario as untreated hypertension can lead to serious complications. Choice C, informing the healthcare provider, is important but should be done after attempting to educate the patient. Choice D, exploring alternative treatment options, may be considered if the patient has concerns or side effects related to the medication, but initially, educating the patient about the importance of medication is key.
