Nursing Elites

1. The healthcare provider is assessing the effectiveness of the drug amiodarone. Which client statement best indicates that the drug has been effective?

• A. I have not had as many spells of angina.
• B. I have not had as much swelling in my ankles lately.
• C. My doctor told me my cholesterol levels were improving with each visit.
• D. I do not notice as many irregular heartbeats as before I started taking this medication.

Correct answer: D

Rationale: The correct answer is option D. The effectiveness of amiodarone is best assessed by a reduction in irregular heartbeats since it is primarily used to treat ventricular dysrhythmias. This drug's main purpose is to control irregular heart rhythms, so a decrease in irregular heartbeats indicates its effectiveness. Options A, B, and C are incorrect because amiodarone is not primarily used to address angina, ankle swelling, or cholesterol levels, so improvements in these areas do not directly reflect the drug's effectiveness.

2. A 6-month-old infant is prescribed digoxin for the treatment of congestive heart failure. Which observation by the practical nurse (PN) warrants immediate intervention for signs of digoxin toxicity?

• A. Apical heart rate of 60 beats/min
• B. Sweating across the forehead
• C. Poor sucking effort
• D. Respiratory rate of 30 breaths/min

Correct answer: A

Rationale: A heart rate of 60 beats/min for a 6-month-old infant warrants immediate intervention as it falls below the normal range. The normal heart rate for a 6-month-old is 80 to 150 beats/min when awake, and a rate of 70 beats/min while sleeping is considered within normal limits. Bradycardia (heart rate <60 beats/min) in infants can be a sign of digoxin toxicity, necessitating prompt evaluation and intervention to prevent adverse effects. Sweating across the forehead (Choice B) is a non-specific symptom and may not directly indicate digoxin toxicity. Poor sucking effort (Choice C) and a respiratory rate of 30 breaths/min (Choice D) are not typically associated with digoxin toxicity and do not require immediate intervention in the context of this question.

3. A client is prescribed an antacid for the treatment of peptic ulcer disease. What is the action of this medication that is effective in treating the client's ulcer?

• A. Decrease in the production of gastric secretions
• B. Production of an adherent barrier over the ulcer
• C. Maintenance of a gastric pH of 3.5 or above
• D. Decrease in the gastric motor activity

Correct answer: C

Rationale: The correct answer is C. Antacids work by neutralizing gastric acids and maintaining a gastric pH of 3.5 or above. This pH level is crucial to prevent the activation of pepsinogen, a precursor to pepsin, which can further damage the ulcer. Choice A is incorrect because antacids do not directly decrease the production of gastric secretions; they neutralize existing acid. Choice B is incorrect as antacids do not form a physical barrier over the ulcer but rather neutralize the acid around it. Choice D is also incorrect as antacids do not affect gastric motor activity but focus on reducing acidity in the stomach.

4. A client receiving enalapril reports a persistent dry cough. The nurse should explain that this side effect is related to which medication action?

• A. It reduces the production of angiotensin II.
• B. It increases the production of angiotensin II.
• C. It causes increased production of bradykinin.
• D. It increases the production of aldosterone.

Correct answer: C

Rationale: The correct answer is C. Enalapril, an ACE inhibitor, inhibits the conversion of angiotensin I to angiotensin II, leading to increased levels of bradykinin. The accumulation of bradykinin is responsible for the persistent dry cough associated with ACE inhibitors like enalapril. Choices A, B, and D are incorrect because enalapril does not directly affect the production of angiotensin II or aldosterone. Instead, it primarily impacts the renin-angiotensin-aldosterone system by inhibiting the conversion of angiotensin I to angiotensin II, leading to bradykinin accumulation.

5. The nurse is caring for a patient with short-term persistent diarrhea. Which class of medication would the nurse anticipate giving?

• A. Lubricants
• B. Probiotics
• C. Adsorbents
• D. Anticholinergics

Correct answer: B

Rationale: Probiotics are the correct choice in this scenario as they help restore normal gut flora, which can be effective in treating diarrhea by promoting a healthy balance of bacteria in the intestines. Lubricants are used to ease bowel movements and are not indicated for treating diarrhea. Adsorbents work by binding to toxins in the gut, which is not the primary mechanism needed for treating diarrhea. Anticholinergics are more commonly used for conditions like overactive bladder and not for short-term persistent diarrhea.
