The client is on dobutamine. Adverse effects of Dobutrex (dobutamine) include the following: Select all that apply.

Correct Answer: C

Rationale: Step-by-step rationale: 1. Dobutamine is a beta-1 adrenergic agonist, which increases heart rate. 2. Tachycardia is a common adverse effect due to increased heart rate. 3. Bradycardia is the opposite effect and not expected with dobutamine. 4. Heart failure is a condition that dobutamine is used to treat, not cause. 5. Respiratory distress is not a typical adverse effect of dobutamine. Summary: Choice C (Tachycardia) is correct because dobutamine increases heart rate. Choices A, B, and D are incorrect because dobutamine does not cause heart failure, bradycardia, or respiratory distress.

Correct Answer: A

Rationale: The correct answer is A: Administer vitamin K as an antidote. An INR of 5.5 indicates the client is at risk for bleeding due to excessive anticoagulation from warfarin. Administering vitamin K helps reverse the effects of warfarin and lowers the INR back to the therapeutic range. Holding the next dose of warfarin (B) is important but not the priority over administering the antidote. Increasing the dose of warfarin (C) would worsen the situation. Administering fresh frozen plasma (D) is not a standard treatment for high INR levels due to warfarin.

Correct Answer: B

Rationale: The correct answer is B: Check the client's blood pressure. When administering a beta blocker to a client with hypertension, the priority assessment is to check the client's blood pressure. Beta blockers lower blood pressure, so monitoring it before administration helps ensure it is within the safe range. Checking the client's heart rate (choice A) is important but not the priority in this scenario. Respiratory rate (choice C) and temperature (choice D) are not directly related to the administration of beta blockers for hypertension.

Correct Answer: A

Rationale: The correct answer is A: Foods high in potassium. Spironolactone is a potassium-sparing diuretic, meaning it helps the body retain potassium. Consuming foods high in potassium while on spironolactone can lead to hyperkalemia, which is an elevated level of potassium in the blood. This can result in serious health complications such as irregular heartbeats and muscle weakness. Therefore, it is crucial for clients on spironolactone to avoid foods high in potassium to prevent these adverse effects. Choices B, C, and D are incorrect because spironolactone does not specifically interact with sodium, calcium, or chloride in a way that necessitates avoiding foods high in these electrolytes.

Correct Answer: A

Rationale: The correct answer is A: Platelet count. Enoxaparin is an anticoagulant that works by preventing blood clots. Monitoring platelet count is crucial to assess for potential thrombocytopenia, a side effect of enoxaparin that can increase the risk of bleeding. Hemoglobin (B) and White blood cell count (C) are not directly affected by enoxaparin. aPTT (D) is not the most important lab value to monitor as enoxaparin does not directly affect this clotting parameter.
