Nursing Elites

1. How is lithium typically administered?

• A. Intravenously
• B. Intramuscularly
• C. Orally
• D. Sublingually

Correct answer: C

Rationale: Lithium is typically administered orally to ensure proper absorption and distribution in the body. By taking lithium orally, it allows the medication to be absorbed through the gastrointestinal tract and distributed effectively. Intravenous and intramuscular routes are not commonly used for lithium administration as they can lead to rapid, unpredictable absorption and increase the risk of toxicity. Sublingual administration is also not the typical route for lithium, as it is usually taken orally for consistent and controlled absorption.

2. What is the antidote for Heparin?

• A. Protamine sulfate
• B. Vitamin K
• C. Naloxone
• D. Toradol

Correct answer: A

Rationale: The correct answer is A: Protamine sulfate. Heparin is an anticoagulant that prevents blood clotting. Protamine sulfate is the antidote for Heparin as it binds to heparin, neutralizing its anticoagulant effects. Vitamin K is not the antidote for Heparin; it is used to reverse the effects of warfarin, another anticoagulant. Naloxone is an opioid antagonist for opioids, and Toradol is a nonsteroidal anti-inflammatory drug (NSAID) for pain relief. Therefore, the correct antidote for Heparin is Protamine sulfate.

3. A client has a new prescription for Atorvastatin. Which of the following instructions should the nurse include?

• A. Take this medication with food.
• B. Avoid drinking grapefruit juice.
• C. Take this medication in the morning.
• D. Increase your intake of potassium-rich foods.

Correct answer: B

Rationale: The correct answer is B: 'Avoid drinking grapefruit juice.' Grapefruit juice can increase the blood levels of Atorvastatin by inhibiting its metabolism in the body, leading to a higher risk of adverse effects, such as muscle pain and liver damage. Therefore, it is important for the client to avoid consuming grapefruit juice while taking Atorvastatin. Choices A, C, and D are incorrect because Atorvastatin can be taken with or without food, at any time of the day, and there is no specific need to increase potassium-rich foods while on this medication.

4. A healthcare professional is educating clients in an outpatient facility about the use of Insulin to treat type 1 Diabetes Mellitus. For which of the following types of insulin should the professional inform the clients to expect a peak effect 1 to 5 hr after administration?

• A. Insulin glargine
• B. NPH insulin
• C. Regular insulin
• D. Insulin lispro

Correct answer: C

Rationale: Regular insulin typically exhibits a peak effect approximately 1 to 5 hours after administration. It is important for clients to be aware of this timing to ensure optimal management of their blood glucose levels. Insulin glargine, NPH insulin, and Insulin lispro have different onset and peak times compared to Regular insulin. Insulin glargine has a slow, steady release with no pronounced peak, NPH insulin peaks around 4 to 12 hours after administration, and Insulin lispro has a rapid onset and a peak effect around 0.5 to 2.5 hours after administration. Therefore, Regular insulin is the correct choice for a peak effect within the specified time frame.

5. Which medication is contraindicated with Nitroglycerin?

• A. Hydrochloroquine
• B. Methylprednisolone
• C. Phenazopyridine
• D. Erectile dysfunction drugs

Correct answer: D

Rationale: The correct answer is D: Erectile dysfunction drugs. Erectile dysfunction drugs are contraindicated with Nitroglycerin because they can potentiate the hypotensive effects of Nitroglycerin, leading to severe hypotension. Choices A, B, and C are incorrect because they are not known to have significant interactions with Nitroglycerin.
