Health Promotion and Maintenance NCLEX PN Questions
1. An adult client undergoes various diagnostic tests to determine the pumping ability of the heart. The nurse notes that the results of these tests indicate that the client's cardiac output is 5 L/min. The nurse makes which conclusion?
- A. The client has a low cardiac output.
- B. The client has a high cardiac output.
- C. The client has a normal cardiac output.
- D. The client will need a blood transfusion.
Correct answer: C
Rationale: A cardiac output of 5 L/min falls within the normal range for a resting adult, which typically ranges between 4 and 6 L/min. Cardiac output is calculated as the stroke volume (volume of blood in each systole) multiplied by the heart rate. Therefore, a cardiac output of 5 L/min is considered normal. Choices A and B are incorrect as they misinterpret the result as either low or high, which is not the case based on the provided information. Choice D is unrelated to the client's cardiac output and thus incorrect.
2. The LPN participates in a home visit for a client with Type 2 Diabetes who has been taking Metformin for 3 years. The client states that for the past 3 months, they have been trying a vegan diet and experiencing fatigue, confusion, and mood changes. What is a likely cause of the new symptoms?
- A. vitamin B12 deficiency
- B. chronic hypoglycemia
- C. vitamin D deficiency
- D. increased tolerance to Metformin
Correct answer: A
Rationale: The correct answer is vitamin B12 deficiency. Long-term use of Metformin can lead to vitamin B12 deficiency, and a vegan diet is low in vitamin B12. Symptoms of vitamin B12 deficiency include anemia, fatigue, confusion, and mood changes. Chronic hypoglycemia is unlikely in a client with Type 2 Diabetes who has been taking Metformin as it typically causes hyperglycemia. Vitamin D deficiency usually presents with symptoms related to bones and muscles, not confusion and mood changes. Increased tolerance to Metformin does not explain the client's new symptoms, which are more indicative of a nutritional deficiency like vitamin B12.
3. The LPN is caring for a client admitted for acute pancreatitis. Which of these medications would be the least appropriate for pain management?
- A. Tylenol
- B. Tramadol
- C. Codeine
- D. Morphine
Correct answer: D
Rationale: Morphine is the least appropriate choice for pain management in pancreatitis due to its potential to cause spasms in the Sphincter of Oddi, which can worsen the client's condition by potentially obstructing the pancreatic duct. Tylenol, Tramadol, and Codeine are more suitable options for pain management in acute pancreatitis as they do not carry the same risk of exacerbating the condition by causing spasms in the Sphincter of Oddi.
4. When assessing the carotid artery of a client with cardiovascular disease, what action should a nurse perform?
- A. Palpating the carotid artery in the upper third of the neck
- B. Palpating both arteries simultaneously to compare amplitude
- C. Listening to the carotid artery, using the bell of the stethoscope to assess for bruits
- D. Instructing the client to take slow, deep breaths while the nurse listens to the carotid artery
Correct answer: C
Rationale: When assessing the carotid artery of a client with cardiovascular disease, the nurse should listen to the carotid artery using the bell of the stethoscope to assess for bruits. This is crucial in detecting abnormal sounds that may indicate underlying pathology. Palpating the carotid artery in the upper third of the neck can trigger a vagal response, leading to a decrease in heart rate, which is undesirable. Palpating both arteries simultaneously can disrupt blood flow to the brain. Instructing the client to take slow, deep breaths is unnecessary and not a standard practice during carotid artery assessment.
5. A nurse is preparing to measure a client's calf circumference. The nurse performs this procedure by performing which action?
- A. Placing a tape measure around the widest point of the lower leg
- B. Measuring 2 inches above the knee and placing the tape measure around the client's leg at this point
- C. Measuring 2 inches above the ankle and placing the tape measure around the client's leg at this point
- D. Measuring 2 inches below the patella and placing the tape measure around the client's leg at this point
Correct answer: A
Rationale: To measure a client's calf circumference accurately, a nurse should place a non-stretchable tape measure around the widest point of the lower leg. It is crucial to ensure that the tape measure is positioned at the same number of centimeters down from a specific landmark, such as the patella, on both legs for consistency. Placing the tape measure 2 inches above the knee (Option B), 2 inches above the ankle (Option C), or 2 inches below the patella (Option D) would not provide an accurate measurement of the calf circumference. Therefore, these options are incorrect choices.
