1. A patient has been taking hydrocodone, an opioid analgesic for their moderate pain, and they have taken more than the prescribed dose. What should you administer as the antidote if they experience toxicity?
- A. Naloxone
- B. N-acetylcysteine
- C. Atropine
- D. Digoxin immune Fab
Correct answer: A
Rationale: Naloxone is the specific antidote for opioid toxicity. It works by blocking the effects of opioids on the central nervous system, thereby reversing symptoms like respiratory depression and sedation. N-acetylcysteine is used for acetaminophen overdose, while atropine is indicated for certain types of poisonings. Digoxin immune Fab is used for digoxin toxicity. Therefore, in the case of opioid toxicity due to hydrocodone overdose, naloxone is the appropriate antidote.
2. A client with a UTI and a history of recurrent infections asks why the provider has not yet prescribed an antibiotic. The nurse should explain that the provider has to wait for the results of which of the following laboratory tests to identify which antibiotic to prescribe?
- A. Gram stain
- B. Culture
- C. Sensitivity
- D. Specific gravity
Correct answer: C
Rationale: In the case of a UTI, a sensitivity test is crucial as it identifies the most effective antibiotic to target the specific microorganism causing the infection. This test helps in prescribing the appropriate antibiotic for successful treatment and preventing antibiotic resistance. While a Gram stain and culture are important in diagnosing a UTI, the sensitivity test specifically determines the most suitable antibiotic. Specific gravity, on the other hand, is not related to identifying the appropriate antibiotic for a UTI.
3. Which of the following diuretics inhibits sodium reabsorption in the kidneys while sparing K+ and hydrogen ions?
- A. Spironolactone
- B. Furosemide
- C. Hydrochlorothiazide
- D. Bumetanide
Correct answer: A
Rationale: Spironolactone is the correct answer as it is classified as a potassium-sparing diuretic. It works by inhibiting sodium reabsorption in the kidneys while promoting the retention of potassium and hydrogen ions. This mechanism of action helps in reducing fluid retention without causing excessive loss of potassium, which is a common side effect of other diuretics. Furosemide (choice B), Hydrochlorothiazide (choice C), and Bumetanide (choice D) are not correct as they are not potassium-sparing diuretics. Furosemide and Bumetanide are loop diuretics that inhibit sodium, potassium, and chloride reabsorption in the loop of Henle. Hydrochlorothiazide is a thiazide diuretic that inhibits sodium and chloride reabsorption in the distal convoluted tubule, leading to potassium loss.
4. A client is taking Furosemide for heart failure. Which of the following findings is a priority to report to the provider?
- A. Weight loss of 1 kg in 24 hours
- B. Blood pressure of 104/60 mm Hg
- C. Potassium level of 3.5 mEq/L
- D. Urine output of 200 mL in 8 hours
Correct answer: D
Rationale: A urine output of 200 mL in 8 hours indicates decreased kidney function, potentially due to Furosemide therapy. This finding can suggest inadequate renal perfusion and impaired drug clearance, necessitating immediate reporting to prevent further complications like electrolyte imbalances and worsening heart failure. Choice A: Weight loss may be expected in heart failure patients due to fluid retention, but it is not an immediate concern. Choice B: A blood pressure of 104/60 mm Hg is slightly low but not a priority compared to the indication of kidney dysfunction. Choice C: A potassium level of 3.5 mEq/L is within the normal range, so it does not require immediate reporting.
5. While caring for a client receiving epoetin alfa to treat anemia, which finding should the nurse monitor for?
- A. Leukocytosis
- B. Hypertension
- C. Hyperkalemia
- D. Fever
Correct answer: B
Rationale: The nurse should monitor the client for hypertension when receiving epoetin alfa. Epoetin alfa stimulates red blood cell production, which can lead to increased blood pressure. Leukocytosis (increased white blood cells) and hyperkalemia (high potassium levels) are not typically associated with epoetin alfa therapy. Fever is also not a common adverse effect of this medication.
