Nursing Elites

1. A healthcare professional in a provider's clinic is caring for a client who reports erectile dysfunction and requests a prescription for sildenafil. Which of the following medications currently prescribed for the client is a contraindication to taking sildenafil?

• A. Isosorbide
• B. Phenytoin
• C. Metronidazole
• D. Prednisone

Correct answer: A

Rationale: Sildenafil is contraindicated with nitrates like isosorbide due to the risk of severe hypotension. Isosorbide is a nitrate that can potentiate the hypotensive effects of sildenafil, leading to a dangerous drop in blood pressure. Therefore, it is essential to avoid concurrent use of isosorbide and sildenafil to prevent adverse effects. Phenytoin, metronidazole, and prednisone do not have significant interactions with sildenafil and are not contraindicated when used together.

2. A client is prescribed Propranolol for a dysrhythmia. Which of the following actions should the nurse plan to take?

• A. Hold Propranolol if the client's apical pulse is greater than 100/min.
• B. Administer Propranolol to decrease the client's blood pressure.
• C. Assist the client with sitting up or standing after taking this medication.
• D. Monitor the client for hypokalemia due to the risk of Propranolol toxicity.

Correct answer: C

Rationale: The correct action the nurse should plan to take when administering Propranolol is to assist the client when sitting up or standing after taking the medication. Propranolol can lead to orthostatic hypotension, causing dizziness upon sudden position changes. It is essential to help the client with position changes to prevent falls or injury. Holding Propranolol if the client's apical pulse is greater than 100/min (Choice A) is incorrect because Propranolol is often used to manage dysrhythmias and slowing down the heart rate. Administering Propranolol to decrease the client's blood pressure (Choice B) is not the primary indication for using this medication. Monitoring the client for hypokalemia due to the risk of Propranolol toxicity (Choice D) is not a direct effect of Propranolol; rather, it is more related to other medications like diuretics.

3. When administering digoxin (Lanoxin) to a patient, the healthcare provider observes various signs and symptoms of an overdose. Which of the following should the healthcare provider give to reverse digoxin toxicity?

• A. Naloxone
• B. Vitamin K
• C. Digibind
• D. Flumazenil

Correct answer: C

Rationale: Digibind, also known as Digoxin immune Fab, is the specific antidote used to treat digoxin toxicity. It works by binding to digoxin in the body, forming a complex that can be excreted by the kidneys, thereby reversing the toxic effects of digoxin overdose. Naloxone is used for opioid overdoses, not digoxin toxicity. Vitamin K is used to reverse the effects of warfarin overdose. Flumazenil is used to reverse the effects of benzodiazepine overdose, not digoxin toxicity.

4. When teaching the parents of a child who has a new prescription for Desipramine, which of the following adverse effects should the nurse instruct the parents is the priority to report to the provider?

• A. Constipation
• B. Suicidal thoughts
• C. Photophobia
• D. Dry mouth

Correct answer: B

Rationale: The priority adverse effect to report when a child is taking Desipramine is suicidal thoughts. Desipramine can lead to an increased risk of suicidal thoughts and behaviors. The nurse should emphasize to the parents the importance of monitoring the child for any signs of worsening depression or suicidal ideation. Prompt reporting of such symptoms can help prevent harm to the child. Choices A, C, and D are not the priority adverse effects associated with Desipramine. While constipation, photophobia, and dry mouth can occur as side effects of Desipramine, they are not as critical as the risk of suicidal thoughts, which requires immediate attention to ensure the safety of the child.

5. Which drug undergoes extensive first-pass hepatic metabolism?

• A. Heparin
• B. Insulin
• C. Propranolol
• D. Nitroglycerin

Correct answer: C

Rationale: Propranolol undergoes extensive first-pass hepatic metabolism in the liver. When administered orally, propranolol is extensively metabolized by the liver before reaching systemic circulation, leading to reduced bioavailability. This process is known as first-pass hepatic metabolism, which significantly affects the drug's effectiveness and necessitates higher oral doses compared to other routes of administration. Heparin (Choice A) is not metabolized by the liver but excreted unchanged by the kidneys. Insulin (Choice B) is a peptide hormone that is not subject to significant first-pass metabolism. Nitroglycerin (Choice D) is primarily metabolized in the blood and tissues, bypassing significant first-pass metabolism in the liver.
