Nursing Elites

1. When taking Digoxin, low levels of what can cause toxicity?

• A. Potassium
• B. Calcium
• C. Sodium
• D. Magnesium

Correct answer: A

Rationale: Low potassium levels can lead to Digoxin toxicity. Digoxin competes with potassium for binding sites on the sodium-potassium pump. When potassium levels are low, there is an increased risk of Digoxin binding and toxicity. Choice B (Calcium) is incorrect because low calcium levels are not directly linked to Digoxin toxicity. Choice C (Sodium) is incorrect as low sodium levels do not cause Digoxin toxicity. Choice D (Magnesium) is incorrect as low magnesium levels do not contribute to Digoxin toxicity.

2. A client with Depression has a new prescription for Venlafaxine. For which of the following adverse effects should the nurse monitor this client? (Select all that apply)

• A. Cough
• B. Dizziness
• C. Decreased libido
• D. B and C

Correct answer: D

Rationale: The correct answer is D: 'B and C.' Venlafaxine, a medication used to treat depression, can lead to adverse effects like dizziness and decreased libido. It is important for the nurse to monitor the client for these potential side effects. Cough and alopecia are not typically associated with Venlafaxine. Therefore, choices A (Cough) and C (Decreased libido) are incorrect. Dizziness and decreased libido are the adverse effects that the nurse should focus on when monitoring a client on Venlafaxine treatment.

3. A client with Angina Pectoris asks the nurse about the next step if one tablet does not relieve Anginal pain after waiting 5 minutes. Which of the following responses should the nurse make?

• A. Take two more sublingual tablets simultaneously.
• B. Call emergency services.
• C. Take a sustained-release nitroglycerin capsule.
• D. Wait another 5 minutes before taking a second sublingual tablet.

Correct answer: B

Rationale: In a situation where Anginal pain persists after taking one sublingual tablet and waiting 5 minutes, it is crucial to call emergency services (911) immediately. This could indicate a myocardial infarction (heart attack) rather than a typical Anginal attack. The client should not take two more sublingual tablets simultaneously without seeking immediate medical help as this could delay appropriate intervention if the pain is due to a heart attack. Taking a sustained-release nitroglycerin capsule is not recommended for immediate relief of acute Anginal pain as it works too slowly. Waiting another 5 minutes before taking a second sublingual tablet is not appropriate if the pain persists, as prompt action is essential in suspected heart-related issues.

4. Which of the following types of insulin is classified as 'long-acting'?

• A. Lispro (Humalog)
• B. NPH (Humulin N)
• C. Regular insulin (Humulin R)
• D. Glargine (Lantus)

Correct answer: D

Rationale: The correct answer is Glargine (Lantus). Glargine is classified as a long-acting insulin due to its slow, steady release over an extended period, making it suitable for basal insulin requirements. It has a duration of action that can last up to 24 hours, helping to maintain stable blood sugar levels throughout the day. Lispro (Humalog) is a rapid-acting insulin, NPH (Humulin N) is an intermediate-acting insulin, and Regular insulin (Humulin R) is a short-acting insulin, so they are not classified as long-acting insulins.

5. How do ACE inhibitors work?

• A. Block the vasoconstrictor and aldosterone effects of angiotensin II at the receptor site
• B. Block stimulation of beta 1 and beta 2 at the receptor sites
• C. Block the conversion of angiotensin I to the vasoconstrictor angiotensin II
• D. None of the above

Correct answer: C

Rationale: ACE inhibitors work by inhibiting the conversion of angiotensin I to angiotensin II. Angiotensin II is a potent vasoconstrictor, and by blocking its production, ACE inhibitors help dilate blood vessels, reduce blood pressure, and decrease the workload of the heart. Choice A is incorrect because it describes the mechanism of action of angiotensin receptor blockers (ARBs), not ACE inhibitors. Choice B is incorrect as it describes beta-blockers, not ACE inhibitors. Choice D is incorrect as ACE inhibitors do have a specific mechanism of action.
