Nursing Elites

1. A histamine (H2)-receptor antagonist will be prescribed for a client. The nurse understands that which medications are H2-receptor antagonists? Select one that doesn't apply.

• A. Nizatidine (Axid)
• B. Ranitidine (Zantac)
• C. Famotidine (Pepcid)
• D. Ibuprofen (Motrin)

Correct answer: D

Rationale: H2-receptor antagonists like Nizatidine, Ranitidine, and Famotidine are used to suppress gastric acid secretion, relieve heartburn symptoms, and prevent complications of peptic ulcer disease. Ibuprofen, on the other hand, is a nonsteroidal anti-inflammatory drug (NSAID) commonly used for pain relief and inflammation, but it is not an H2-receptor antagonist. It is essential to differentiate between these medication classes to ensure appropriate treatment for gastrointestinal conditions.

2. A client is to begin a 6-month course of therapy with isoniazid (INH). A nurse plans to teach the client to:

• A. Avoid drinking alcohol.
• B. Report yellow eyes or skin immediately.
• C. Avoid Swiss or aged cheeses.
• D. Avoid vitamin supplements during therapy.

Correct answer: B

Rationale: When a client is on isoniazid (INH) therapy, they should be instructed to report any signs of hepatitis, such as yellowing of the eyes or skin, immediately. Alcohol consumption should be avoided during INH therapy due to the risk of hepatotoxicity. Foods high in tyramine, such as Swiss or aged cheeses, should also be avoided to prevent adverse reactions. Additionally, while on INH therapy, it is essential to avoid vitamin supplements containing pyridoxine (vitamin B6) to prevent potential interactions.

3. Intravenous heparin therapy is prescribed for a client. While implementing this prescription, a nurse ensures that which of the following medications is available on the nursing unit?

• A. Protamine sulfate
• B. Potassium chloride
• C. Phytonadione (vitamin K)
• D. Aminocaproic acid (Amicar)

Correct answer: A

Rationale: Protamine sulfate is the antidote for heparin, working to reverse its effects in case of excessive bleeding. It should be readily available when administering heparin to manage any potential bleeding complications effectively. Potassium chloride is not the antidote for heparin and is typically used to correct low potassium levels. Phytonadione (vitamin K) is used to reverse the effects of warfarin, not heparin. Aminocaproic acid (Amicar) is used to treat or prevent excessive bleeding but is not the antidote for heparin.

4. A client is learning how to mix regular insulin and NPH insulin in the same syringe. Which action, if performed by the client, indicates the need for further teaching?

• A. Withdraws the NPH insulin first
• B. Withdraws the regular insulin first
• C. Injects air into the NPH insulin vial first
• D. Injects an amount of air equal to the desired dose of insulin into the vial

Correct answer: A

Rationale: When mixing regular insulin with another insulin preparation, it is crucial to withdraw the regular insulin first to prevent contamination. NPH insulin should be drawn after the regular insulin to maintain the integrity of each insulin type. Therefore, if the client withdraws the NPH insulin first, it indicates the need for further teaching. Choice B is correct as withdrawing regular insulin first is the appropriate step. Choice C is incorrect as air should be injected into the vial containing the regular insulin to maintain pressure. Choice D is incorrect as injecting air equal to the desired dose of insulin into the vial is a correct step in preparing the insulin for withdrawal.

5. A client has been started on long-term therapy with rifampin (Rifadin). A nurse teaches the client that the medication:

• A. Should always be taken with food or antacids
• B. Should be double-dosed if one dose is forgotten
• C. Causes orange discoloration of sweat, tears, urine, and feces
• D. May not be discontinued independently if symptoms are gone in 3 months

Correct answer: C

Rationale: Rifampin causes orange-red discoloration of body secretions, including sweat, tears, urine, and feces. It can also permanently stain soft contact lenses. It is essential to take rifampin exactly as directed and not discontinue it without consulting the healthcare provider.
