1. Heparin 20,000 units in 500 ml D5W at 50 ml/hour has been infusing for 5.5 hours. How much heparin has the client received?

• A. 11,000 units.
• B. 13,000 units.
• C. 15,000 units.
• D. 17,000 units.

Correct answer: A

Rationale: To calculate the total amount of heparin received, multiply the infusion rate (50 ml/hour) by the total infusion time (5.5 hours). This results in 275 ml of the solution infused. Since there are 20,000 units of heparin in 500 ml, there are 800 units per ml. Therefore, 275 ml contains 220,000 units. However, the heparin is diluted in 500 ml, so the client has received half of this amount, which is 110,000 units. Therefore, the correct answer is 11,000 units. Choices B, C, and D are incorrect as they do not reflect the correct calculation based on the provided information.

2. The healthcare professional prepares a 1,000 ml IV of 5% dextrose and water to be infused over 8 hours. The infusion set delivers 10 drops per milliliter. The healthcare professional should regulate the IV to administer approximately how many drops per minute?

• A. 80
• B. 8
• C. 21
• D. 25

Correct answer: C

Rationale: To calculate the drops per minute for the IV infusion, first determine the total drops to be infused over 8 hours. 1,000 ml to be infused over 8 hours means 125 ml per hour (1000 ml / 8 hours = 125 ml/hr). Since the infusion set delivers 10 drops per ml, 125 ml/hr x 10 drops/ml = 1250 drops/hr. To find drops per minute, divide the drops per hour by 60 (minutes in an hour): 1250 drops/hr / 60 minutes = 20.83 drops/minute, which rounds up to 21 drops per minute (Option C). This rate ensures the correct infusion rate over 8 hours. Choices A, B, and D are incorrect calculations and do not provide the appropriate infusion rate needed to administer the IV over the specified time period.

3. During a neurological assessment, a healthcare provider is evaluating a client's balance. Which of the following examinations should the provider use for this purpose?

• A. Romberg test
• B. Deep tendon reflexes
• C. Mini-Mental State Examination
• D. Babinski reflex

Correct answer: A

Rationale: The Romberg test is utilized to assess the client's balance and proprioception by having them stand with their eyes closed. This test helps evaluate sensory ataxia, a condition where an individual's balance is affected due to impaired sensory input. Deep tendon reflexes (Choice B) are assessed by tapping a tendon with a reflex hammer to evaluate the integrity of the spinal cord and peripheral nerves; this is not directly related to balance assessment. The Mini-Mental State Examination (Choice C) is a cognitive screening tool used to assess cognitive impairment or dementia, not balance. The Babinski reflex (Choice D) is elicited by stroking the sole of the foot to assess neurologic function, particularly in the corticospinal tract, and is not specific to balance evaluation.

4. The healthcare provider is assessing a client with a diagnosis of asthma. Which assessment finding would be most concerning?

• A. Wheezing
• B. Shortness of breath
• C. Use of accessory muscles
• D. Cough with sputum production

Correct answer: C

Rationale: The most concerning assessment finding in a client with asthma is the use of accessory muscles. This indicates that the client is working harder to breathe, which could signify respiratory distress. Wheezing, choice A, is a common finding in asthma and indicates narrowed airways but may not necessarily imply immediate distress. Shortness of breath, choice B, is also common in asthma but may not be as concerning as the use of accessory muscles. Cough with sputum production, choice D, can occur in asthma exacerbations but may not be as critical as signs of increased work of breathing like the use of accessory muscles.

5. During a patient assessment, which principle should be a priority?

• A. Foot care is always important.
• B. Daily bathing is always important.
• C. Hygiene needs are always important.
• D. Critical thinking is always important.

Correct answer: D

Rationale: During a patient assessment, critical thinking is a priority because a patient's condition can change rapidly, necessitating continuous critical thinking and adaptation of nursing interventions. While foot care, daily bathing, and hygiene needs are important components of patient care, they may not always take precedence over critical thinking, which guides the nurse in making timely and appropriate decisions based on the patient's current condition and needs. Therefore, critical thinking stands out as the most crucial principle during patient assessments.
