Correct Answer: B

Rationale: The correct answer is B: Peripheral edema. In heart failure, the heart's inability to pump effectively can lead to fluid backup, causing swelling in the extremities, known as peripheral edema. Monitoring for peripheral edema is crucial as it is a common sign of worsening heart failure. Choices A, C, and D are incorrect because increased energy, elevated heart rate, and improved lung sounds are not typical findings in heart failure. Increased energy is not usually associated with heart failure, an elevated heart rate may occur as a compensatory mechanism but is not a direct sign of heart failure, and improved lung sounds are not expected in heart failure which often presents with crackles or wheezes due to pulmonary congestion.

Correct Answer: B

Rationale: The correct answer is to check the heart rate first before administering digoxin. Digoxin is a medication that directly affects the heart, so it is crucial to ensure that the heart rate is within the appropriate range before giving the dose. If the heart rate is below 60 bpm, administering digoxin could lead to toxicity. Assessing blood pressure (Choice A) is important but not the first priority when preparing to administer digoxin. Monitoring potassium levels (Choice C) is also crucial for patients on digoxin, but it is not the initial step. Reviewing the medication order (Choice D) is necessary but can be done after checking the heart rate.

Correct Answer: C

Rationale: The correct answer is Gonorrhea. Gonorrhea is a reportable sexually transmitted disease, and healthcare providers must report cases to the CDC to track and prevent outbreaks. Influenza, Tuberculosis, and Hepatitis B are not nationally notifiable infectious diseases. Influenza is monitored for its epidemiology and impact on public health, but it is not classified as nationally notifiable. Tuberculosis and Hepatitis B are not included in the list of diseases that healthcare providers are required to report to public health authorities.

Correct Answer: B

Rationale: The correct answer is B: 'Take it once a week.' Alendronate is typically taken once a week to treat osteoporosis. It should be taken on an empty stomach in the morning with a full glass of water. Choice A is incorrect because alendronate should be taken on an empty stomach, not with food. Choice C is incorrect because alendronate should be taken in the morning, not at bedtime. Choice D is unrelated to alendronate use and not a common side effect associated with this medication.

Correct Answer: A

Rationale: The correct answer is to assess blood pressure first. Losartan is an angiotensin receptor blocker used to lower blood pressure. Assessing the patient's blood pressure before administering losartan is crucial to ensure it is not already too low, which could lead to hypotension. Assessing heart rate (choice B) is important but not the priority when administering losartan. Serum potassium levels (choice C) and liver function (choice D) are also important assessments, but they are not the primary concern before administering losartan.
