Nursing Elites

1. What can cause a low pulse oximetry reading?

• A. Hyperthermia
• B. Increased hemoglobin level
• C. Inadequate peripheral circulation
• D. Low altitudes

Correct answer: C

Rationale: Inadequate peripheral circulation can cause a low pulse oximetry reading by limiting blood flow to the area being measured, leading to inaccurate oxygen saturation readings. Hyperthermia (choice A) is an elevated body temperature and does not directly affect pulse oximetry readings. An increased hemoglobin level (choice B) would actually lead to higher oxygen-carrying capacity in the blood, resulting in normal or increased pulse oximetry readings. Low altitudes (choice D) typically do not cause low pulse oximetry readings unless there are other underlying conditions affecting oxygen levels.

2. While providing education about the use of lorazepam, which of the following should be included?

• A. It can cause dependency
• B. It can be taken with alcohol
• C. It has no side effects
• D. It is a stimulant

Correct answer: A

Rationale: The correct answer is A: 'It can cause dependency.' Lorazepam is a benzodiazepine known to cause dependency, so it is crucial for clients to be informed about this potential risk. Choice B is incorrect as combining lorazepam with alcohol can lead to increased sedation and other adverse effects. Choice C is incorrect because lorazepam, like any medication, can have side effects such as drowsiness, dizziness, or confusion. Choice D is also incorrect as lorazepam is a sedative-hypnotic medication, not a stimulant.

3. A nurse is in the emergency department monitoring the hydration status of a client receiving oral rehydration. What should the nurse intervene for?

• A. Heart rate 120/min
• B. Urine output 30 mL/hour
• C. Blood pressure 110/70 mmHg
• D. Skin turgor is normal

Correct answer: A

Rationale: A heart rate of 120/min may indicate dehydration or inadequate hydration, prompting the need for IV fluid replacement. Elevated heart rate is a sensitive indicator of dehydration as the body attempts to maintain cardiac output. Urine output of 30 mL/hour is within the normal range (30 mL/hour is the minimum acceptable urine output for an adult). Blood pressure of 110/70 mmHg is within the normal range. Normal skin turgor is a positive sign indicating adequate hydration.

4. A nurse is teaching a client about the use of atorvastatin. Which of the following should be included?

• A. Monitor for muscle pain
• B. It can cause weight gain
• C. It is safe during pregnancy
• D. It is an anticoagulant

Correct answer: A

Rationale: The correct answer is A: 'Monitor for muscle pain.' Atorvastatin can cause muscle pain and liver function abnormalities, so clients should be monitored for these side effects. Choice B is incorrect because atorvastatin is not known to cause weight gain. Choice C is incorrect as atorvastatin is contraindicated during pregnancy due to potential harm to the fetus. Choice D is incorrect because atorvastatin is a statin medication used to lower cholesterol levels, not an anticoagulant.

5. A healthcare provider is educating a patient on the use of alendronate. Which of the following should be included?

• A. Take it with food
• B. Take it once a week
• C. It can be taken at bedtime
• D. Monitor for increased appetite

Correct answer: B

Rationale: The correct answer is B: 'Take it once a week.' Alendronate is typically taken once a week to treat osteoporosis. It should be taken on an empty stomach in the morning with a full glass of water. Choice A is incorrect because alendronate should be taken on an empty stomach, not with food. Choice C is incorrect because alendronate should be taken in the morning, not at bedtime. Choice D is unrelated to alendronate use and not a common side effect associated with this medication.
