1. What is the action of Nitroglycerin?

• A. Dilates the Bronchi
• B. Reduces Blood Glucose
• C. Reduces Nausea
• D. Dilates Coronary Arteries

Correct answer: D

Rationale: Nitroglycerin acts by dilating the coronary arteries, leading to increased blood flow and oxygen supply to the heart. This helps in relieving angina symptoms by reducing the heart's workload and improving blood supply to the myocardium. Choices A, B, and C are incorrect because Nitroglycerin's primary action is not related to dilating bronchi, reducing blood glucose, or reducing nausea.

2. A client is being taught about Terbutaline. Which statement by the client indicates understanding of the teaching?

• A. This medication will stop my contractions.
• B. This medication will prevent vaginal bleeding.
• C. This medication will promote blood flow to my baby.
• D. This medication will increase my prostaglandin production.

Correct answer: A

Rationale: The correct answer is A. Terbutaline works by blocking beta2-adrenergic receptors, leading to uterine smooth muscle relaxation and stopping contractions. Therefore, the client demonstrating understanding by recognizing that the medication will stop contractions is the most accurate response. Choices B, C, and D are incorrect because Terbutaline is primarily used to inhibit contractions in preterm labor, not prevent vaginal bleeding, promote blood flow to the baby, or increase prostaglandin production.

3. When educating a client with a new prescription for albuterol, which instruction should the nurse include?

• A. Use the inhaler every 4 hours.
• B. Shake the inhaler before use.
• C. Take a deep breath before inhaling the medication.
• D. Use a spacer when using the inhaler.

Correct answer: B

Rationale: Shaking the albuterol inhaler before use is essential to ensure that the medication is evenly mixed and properly delivered when inhaled. This maximizes the effectiveness of the medication in opening the airways and relieving symptoms of bronchospasm.

4. A healthcare provider in a clinic is monitoring serum electrolytes for four older adult clients who take digoxin. Which of the following electrolyte values increases a client's risk for Digoxin toxicity?

• A. Calcium 9.2 mg/dL
• B. Calcium 10.3 mg/dL
• C. Potassium 3.4 mEq/L
• D. Potassium 4.8 mEq/L

Correct answer: C

Rationale: Potassium 3.4 mEq/L is below the expected reference range, which increases the risk for digoxin toxicity. Low potassium levels can lead to fatal dysrhythmias, particularly in older clients taking Digoxin. Hypokalemia potentiates the effects of Digoxin, making the heart more sensitive to its toxic effects. Monitoring and correcting electrolyte imbalances, especially low potassium levels, are crucial to prevent adverse effects of digoxin therapy. Calcium levels do not directly influence digoxin toxicity, so choices A and B are incorrect. High potassium levels, as in choice D, are less likely to increase the risk of digoxin toxicity compared to low potassium levels.

5. 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.
