A nurse is preparing to administer potassium chloride 10 mEq IV over 1 hr to a client. Available is potassium chloride 10 mEq in 100 mL of 0.9% sodium chloride. The nurse should set the infusion pump to deliver how many mL/hr? (Round the answer to the nearest whole number.)
- A. 50 mL/hr
- B. 75 mL/hr
- C. 100 mL/hr
- D. 125 mL/hr
Correct Answer: C
Rationale: To calculate the infusion rate, we need to use the formula: (Desired dose ÷ Volume) x 60 minutes. In this case, the desired dose is 10 mEq over 1 hour, and the volume is 100 mL.
So, (10 ÷ 100) x 60 = 6 mL/hr. Therefore, the nurse should set the infusion pump to deliver 100 mL/hr. This ensures the correct administration of potassium chloride over the specified time frame.
Choice A (50 mL/hr) and B (75 mL/hr) are incorrect as they would result in the underdosing of potassium chloride. Choice D (125 mL/hr) is incorrect as it would result in the overdosing of potassium chloride. The correct answer, C (100 mL/hr), ensures the proper administration of the medication within the specified parameters.

A nurse is teaching a client how to obtain a specimen at home for a fecal occult blood test. Which of the following actions should the nurse instruct the client to take for 3 days prior to collecting the specimen?
- A. Avoid eating red meat.
- B. Increase fiber intake.
- C. Take an iron supplement.
- D. Drink grapefruit juice.
Correct Answer: A
Rationale: The correct answer is A: Avoid eating red meat. Red meat can cause false positives in fecal occult blood tests due to the presence of heme iron which can be mistaken for blood. Instructing the client to avoid red meat for 3 days prior to collecting the specimen helps to ensure the accuracy of the test results.
Summary:
B: Increasing fiber intake does not directly impact the accuracy of the fecal occult blood test.
C: Taking an iron supplement can interfere with the test results by increasing the amount of iron in the stool, leading to false positives.
D: Drinking grapefruit juice is not relevant to the accuracy of the fecal occult blood test.
A nurse is caring for a client who is receiving vancomycin intermittent IV bolus therapy for methicillin-resistant Staphylococcus aureus (MRSA). Which of the following findings is an indication to the nurse that the client is experiencing an adverse effect of the medication?
- A. The client reports ringing in the ears.
- B. The client is becoming flushed.
- C. The client reports increased thirst.
- D. The client has a decreased urine output.
Correct Answer: B
Rationale: The correct answer is B: The client is becoming flushed. Flushing is a common adverse effect of vancomycin, indicating a possible allergic reaction or infusion reaction. Flushing can be a sign of red man syndrome, a severe reaction to vancomycin. The nurse should monitor closely and report this finding to the healthcare provider.
Incorrect Answer Rationale:
A: The client reports ringing in the ears - this is a potential adverse effect of vancomycin, but not as critical as flushing.
C: The client reports increased thirst - this is not typically associated with vancomycin adverse effects.
D: The client has a decreased urine output - this may indicate nephrotoxicity, a known side effect of vancomycin, but flushing is more indicative of an immediate adverse reaction.
A nurse is assessing a client who has an exacerbation of diverticular disease. In which of the following quadrants should the nurse anticipate the client to be experiencing abdominal pain?
- A. Right lower quadrant
- B. Left lower quadrant
- C. Upper left quadrant
- D. Mid-epigastric area
Correct Answer: B
Rationale: The correct answer is B: Left lower quadrant. Diverticular disease commonly causes pain in the left lower quadrant due to inflammation or infection of the diverticula, small pouches that can develop in the colon wall. This area corresponds to the location of the descending and sigmoid colon, where most diverticula occur. Pain in the right lower quadrant (choice A) is more indicative of appendicitis. Upper left quadrant pain (choice C) is more likely related to conditions involving the spleen or stomach. Mid-epigastric pain (choice D) is typically associated with issues related to the stomach or pancreas.
A nurse is caring for a client who is intubated and receiving mechanical ventilation for heroin toxicity. Which of the following assessments is the nurses priority?
- A. Monitor urine output.
- B. Assess level of consciousness.
- C. Check ABGs.
- D. Monitor for signs of withdrawal.
Correct Answer: C
Rationale: The correct answer is C: Check ABGs. In this scenario, monitoring the client's arterial blood gases (ABGs) is the priority assessment because heroin toxicity can lead to respiratory depression and impaired gas exchange. ABGs provide crucial information about the client's oxygenation and ventilation status, which is essential for managing mechanical ventilation and preventing respiratory complications. Monitoring urine output (A) is important but not the priority in a client with potential respiratory compromise. Assessing level of consciousness (B) is significant, but ensuring adequate oxygenation takes precedence. Monitoring for signs of withdrawal (D) is important but not as urgent as assessing respiratory status.
A nurse is providing teaching to a group of clients about the prevention of coronary artery disease. Which of the following information should the nurse include in the teaching?
- A. Walk 30 min daily at a comfortable pace.
- B. Avoid all sources of dietary fat.
- C. Increase sodium intake to prevent dehydration.
- D. Only exercise if experiencing symptoms.
Correct Answer: A
Rationale: Correct Answer: A: Walk 30 min daily at a comfortable pace.
Rationale: Regular physical activity, such as walking, helps prevent coronary artery disease by improving cardiovascular health, maintaining a healthy weight, and reducing stress. Walking for 30 minutes daily at a comfortable pace can improve circulation, lower blood pressure, and reduce the risk of developing heart disease.
Summary of other choices:
B: Avoiding all sources of dietary fat is not recommended as the body needs healthy fats for various functions.
C: Increasing sodium intake does not prevent coronary artery disease and can actually contribute to hypertension, a risk factor for the disease.
D: Only exercising when experiencing symptoms is not proactive in preventing coronary artery disease and may lead to missed opportunities for prevention.
