1. In hanging a parenteral IV fluid that is to be infused by gravity, rather than with an infusion pump, the nurse notes that the IV tubing is available in different drop factors. Which tubing is a microdrop set?

• A. 15 drops per milliliter
• B. 60 drops per milliliter
• C. 20 drops per milliliter
• D. 10 drops per milliliter

Correct answer: B

Rationale: A microdrop set delivers 60 drops per milliliter of IV fluid. This allows for a more precise control of the infusion rate. The correct choice is B because it provides the desired microdrop rate. Choices A, C, and D are incorrect. A delivers 15 drops per milliliter, which is a macrodrop set. C delivers 20 drops per milliliter, also a macrodrop set. D delivers 10 drops per milliliter, another macrodrop set. Therefore, the correct choice for a microdrop set is B.

2. A healthcare professional is reviewing a patient's serum glucose levels. Which of the following scenarios would indicate abnormal serum glucose values for a 30-year-old male?

• A. 70 mg/dL
• B. 55 mg/dL
• C. 110 mg/dL
• D. 100 mg/dL

Correct answer: B

Rationale: The correct answer is 55 mg/dL. The standard range for serum glucose levels is typically 60-115 mg/dL. A serum glucose level of 55 mg/dL falls below this range, indicating hypoglycemia. Options A, C, and D are within the standard range for serum glucose levels and would not be considered abnormal for a 30-year-old male.

3. Which of the following viruses is most likely to be acquired through casual contact with an infected individual?

• A. influenza virus
• B. herpes virus
• C. cytomegalovirus (CMV)
• D. human immunodeficiency virus (HIV)

Correct answer: A

Rationale: The correct answer is influenza virus. Influenza virus is most likely to be acquired through casual contact with an infected individual as it is transmitted through respiratory droplets. Herpes virus is primarily transmitted by direct contact, such as skin-to-skin contact, making it less likely to be acquired through casual contact. HIV is mainly transmitted through blood and body fluids like semen and vaginal fluids, not through casual contact. Cytomegalovirus (CMV) is an opportunistic infection commonly affecting immunocompromised individuals and is usually transmitted through close personal contact, not casual contact.

4. The client develops a tension pneumothorax. Assessment is expected to reveal?

• A. Sudden hypertension and bradycardia
• B. Productive cough with yellow mucus
• C. Tracheal deviation and dyspnea
• D. Sudden development of profuse hemoptysis and weakness

Correct answer: C

Rationale: In a tension pneumothorax, the trachea deviates to the unaffected side due to increased pressure in the affected pleural space, causing respiratory distress. Dyspnea is a hallmark symptom as the lung on the affected side collapses, leading to difficulty in breathing. Sudden hypertension and bradycardia (Choice A) are not typical findings of tension pneumothorax. Productive cough with yellow mucus (Choice B) is more suggestive of respiratory infections rather than a tension pneumothorax. Sudden development of profuse hemoptysis and weakness (Choice D) is not characteristic of tension pneumothorax presentation.

5. A client needs to rapidly achieve a therapeutic plasma drug concentration of a medication. Rather than wait for steady state to be achieved, the physician might order:

• A. a maintenance dose.
• B. a loading dose.
• C. a medication with no first-pass effect.
• D. the medication to be given intravenously.

Correct answer: B

Rationale: To rapidly achieve a therapeutic plasma drug concentration, a loading or priming dose is ordered. This dose quickly establishes the desired drug level. It is calculated by multiplying the volume of distribution by the desired plasma drug concentration. A maintenance dose, like choice A, is used to maintain the therapeutic level after the loading dose. Waiting for steady state without a loading dose would take five drug half-lives. Choice C, a medication with no first-pass effect, does not directly address the need for rapid attainment of therapeutic levels. While intravenous administration (choice D) offers excellent bioavailability, a single dose by this route may not achieve the desired therapeutic plasma concentration as rapidly as a loading dose.
