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. During an assessment, a healthcare professional observes significant tenting of the skin over an older adult client's forearm. What factor should the healthcare professional primarily consider as a cause for this finding?

• A. Thin, parchment-like skin
• B. Loss of adipose tissue
• C. Dehydration
• D. Diminished skin elasticity

Correct answer: C

Rationale: Dehydration is the primary factor to consider in this scenario. Dehydration leads to decreased skin turgor and tenting, where the skin does not return to its normal position when pinched. While thin, parchment-like skin, loss of adipose tissue, and diminished skin elasticity can contribute to skin changes, they are not the primary cause of the significant tenting observed.

3. A client with lower extremity weakness is being taught a four-point crutch gait by a nurse. Which of the following instructions should the nurse include in the teaching?

• A. Bear weight on both legs.
• B. Move the crutches and the weak leg in unison.
• C. Advance the crutches and the strong leg simultaneously.
• D. Move the crutches forward, then move one leg at a time.

Correct answer: D

Rationale: The correct technique for a four-point crutch gait involves moving the crutches forward, then moving one leg at a time. This method provides stability and support by alternating movement between the crutches and legs. Choice A is incorrect because bearing weight on both legs simultaneously is not the correct method for a four-point gait. Choice B is incorrect as moving the crutches and weak leg together does not provide the required stability. Choice C is incorrect as advancing the crutches and strong leg together does not promote the alternating movement needed for a four-point gait.

4. Which of the following manifestations confirms the presence of pediculosis capitis in students?

• A. Scratching the head more than usual
• B. Flakes evident on a student's shoulders
• C. Oval pattern occipital hair loss
• D. Whitish oval specks sticking to the hair

Correct answer: D

Rationale: The correct answer is D. Whitish oval specks sticking to the hair shaft are nits, which are a definitive sign of pediculosis capitis (head lice). A: Scratching the head more than usual is a common symptom but not confirmatory of head lice infestation. B: Flakes evident on a student's shoulders may indicate dandruff or dry scalp, not necessarily head lice. C: Oval pattern occipital hair loss is not a typical manifestation of pediculosis capitis.

5. During a mass casualty event, a nurse is caring for multiple clients. Which of the following clients is the nurse’s priority?

• A. A client who received crush injuries to the chest and abdomen and is expected to die.
• B. A client who has a 4-inch laceration to the head.
• C. A client who has partial-thickness and full-thickness burns to his face, neck, and chest.
• D. A client who has a fractured fibula and tibia.

Correct answer: C

Rationale: During a mass casualty event, the priority client for the nurse is the one with partial-thickness and full-thickness burns to the face, neck, and chest. Clients with severe burns in critical areas require immediate attention due to the potential for life-threatening complications such as airway compromise, fluid loss, and infection. Crush injuries and fractures, although serious, are generally less urgent in comparison and can be managed after addressing the burns. Therefore, the client with burns to the face, neck, and chest should be the nurse's priority over the other clients described.
