Nursing Elites

1. A patient is kept off food and fluids for 10 hours before surgery. His oral temperature at 8 a.m. is 99.8°F (37.7°C). This temperature reading probably indicates:

• A. Infection
• B. Hypothermia
• C. Anxiety
• D. Dehydration

Correct answer: D

Rationale: A patient being kept off food and fluids before surgery can lead to dehydration. Dehydration can cause a slight increase in body temperature, which could explain the elevated oral temperature reading of 99.8°F (37.7°C) in this scenario. Infections are more likely to cause higher fevers, hypothermia would present with a lower temperature, and anxiety typically does not directly affect body temperature in this manner.

2. After 1 week of hospitalization, Mr. Gray develops hypokalemia. Which of the following is the most significant symptom of his disorder?

• A. Lethargy
• B. Increased pulse rate and blood pressure
• C. Muscle weakness
• D. Muscle irritability

Correct answer: C

Rationale: Muscle weakness is a hallmark symptom of hypokalemia. Hypokalemia refers to low levels of potassium in the blood, which can affect muscle function. The decreased potassium levels can lead to muscle weakness, cramping, and even paralysis. These symptoms can impact various muscle groups in the body, making muscle weakness the most significant symptom to monitor and address in patients with hypokalemia.

3. A healthcare professional is receiving a telephone prescription from a provider for a client who requires additional medication for pain control. Which of the following entries should the healthcare professional make in the medical record?

• A. Morphine 3 mg Subcutaneous every 4 hr. PRN for pain.
• B. Morphine 3 mg Subcutaneous
• C. Morphine 3.0 mg subcutaneously every 4 hr. PRN for pain.
• D. Morphine 3 mg Subcutaneous q 4 hr. PRN for pain.

Correct answer: D

Rationale: The correct entry for documenting the prescription for morphine is 'Morphine 3 mg Subcutaneous'. This entry accurately specifies the medication, dosage, route of administration, and frequency as prescribed by the provider. Options A, C, and D contain minor errors such as missing units of measurement or incorrect abbreviations, which could lead to misinterpretation or potential medication errors. Therefore, the most appropriate and accurate choice is 'Morphine 3 mg Subcutaneous'.

4. Which of the following vascular system changes result from aging?

• A. Increased peripheral resistance of the blood vessels
• B. Decreased blood flow
• C. Increased workload of the left ventricle
• D. All of the above

Correct answer: D

Rationale: As individuals age, various changes occur in the vascular system. These changes include increased peripheral resistance of the blood vessels, decreased blood flow, and an increased workload of the left ventricle. Therefore, all the listed changes result from aging, making option D, 'All of the above,' the correct answer.

5. During a Romberg test, the patient is asked to assume which position?

• A. Sitting
• B. Standing
• C. Genupectoral
• D. Trendelenburg

Correct answer: B

Rationale: During a Romberg test, the patient is asked to stand with feet together and arms at the sides. The test evaluates proprioception and vestibular function by assessing the patient's ability to maintain balance with eyes closed. Asking the patient to stand helps to detect any balance issues or disturbances in the absence of visual input.
