A nurse is preparing a presentation about basic nutrients for a group of high school athletes. She should explain that which of the following is the body's priority energy reserve?
- A. Fat
- B. Protein
- C. Glycogen
- D. Carbohydrates
Correct Answer: D
Rationale: The correct answer is D: Carbohydrates. Carbohydrates are the body's priority energy reserve because they are the primary source of energy for the body, especially during high-intensity activities like sports. When consumed, carbohydrates are broken down into glucose, which is used for immediate energy or stored as glycogen in muscles and the liver for later use. Fat is a long-term energy reserve but is not as readily accessible as carbohydrates for quick energy. Protein is primarily used for building and repairing tissues, not as a main energy source. Glycogen is a stored form of carbohydrates in the body, not the primary energy reserve.

A nurse is preparing to administer methylprednisolone acetate (Depo-Medrol) 10 mg by IV bolus. The amount available is 40 mg/mL. How many mL should the nurse administer?
Correct Answer: 0.3
Rationale: Correct Answer: 0.3 mL
Rationale:
1. Calculate the total dose needed: 10 mg.
2. Determine the concentration: 40 mg/mL.
3. Use the formula: dose needed / concentration available = volume to administer.
4. Plug in the values: 10 mg / 40 mg/mL = 0.25 mL.
5. Round up to the nearest practical dose increment: 0.3 mL.
Summary:
Choice A (0.5 mL): Incorrect, as it does not accurately calculate the volume needed.
Choices B-G: Irrelevant, as they do not follow the correct calculation method.
A nurse is caring for a client who will perform fecal occult blood testing at home. Which of the following information should the nurse include when explaining the procedure to the client?
- A. Eating more protein is optimal prior to testing
- B. One stool specimen is sufficient for testing
- C. A red color change indicates a positive test
- D. The specimen cannot be contaminated
Correct Answer: D
Rationale: The correct answer is D because a contaminated specimen can lead to false results. The client should be instructed to avoid contaminating the specimen with urine, water, or toilet bowl cleaners. Choice A is incorrect because protein intake does not affect the test. Choice B is incorrect as multiple stool specimens are usually required. Choice C is incorrect as a blue color change indicates a positive test, not red.
A nurse is caring for a client diagnosed w/severe acute respiratory syndrome (SARS). The nurse is aware that health care professionals are required to report communicable & infectious diseases. Which of the following illustrate the rationale for reporting? Select all.
- A. Planning & evaluating control & prevention strategies
- B. Determining public health priorities
- C. Ensuring proper medical treatment
- D. Identifying endemic disease
- E. Monitoring for common-source outbreaks
Correct Answer: A, B, C, E
Rationale: The correct answers are A, B, C, and E. Reporting communicable diseases like SARS is crucial for planning and evaluating control and prevention strategies. It helps in determining public health priorities by identifying trends and areas that require attention. Reporting ensures proper medical treatment for the affected individuals and their contacts, preventing further spread. Additionally, monitoring for common-source outbreaks allows for timely intervention to limit the spread of the disease. Choices D, F, and G are incorrect as they do not directly relate to the rationale for reporting communicable diseases in this context.
A nurse is teaching an adult client how to administer ear drops. Which of the following statements by the client indicates understanding of the proper technique?
- A. I will straighten my ear canal by pulling my ear down & back.
- B. I will gently apply pressure w/my finger to the tragus of my ear after putting in the drops.
- C. I will insert the nozzle of the ear drop bottle snug into my ear before squeezing the drops in.
- D. After the drops are in, I will place a cotton ball all the way into my ear canal.
Correct Answer: B
Rationale: The correct answer is B: "I will gently apply pressure with my finger to the tragus of my ear after putting in the drops." This statement indicates understanding of the proper technique because applying pressure to the tragus helps the ear drops to reach the ear canal. The tragus is a small cartilaginous projection in front of the ear canal that, when pressed, helps to facilitate the passage of the drops into the ear. This action ensures proper distribution of the medication for effective treatment.
Other choices are incorrect:
A: Pulling the ear down and back is a technique used for administering ear drops in children, not adults.
C: Inserting the nozzle snug into the ear can cause injury to the ear canal and eardrum.
D: Placing a cotton ball all the way into the ear canal can prevent the drops from reaching the ear canal and may cause blockage.
A nurse is caring for an older adult client who is at risk for developing pressure ulcers. Which of the following interventions should the nurse use to help maintain the integrity of the client's skin? Select all.
- A. Keep the head of the bed elevated 30 degrees
- B. Massage the client's bony prominences often
- C. Apply cornstarch liberally to the skin after bathing
- D. Have the client sit on a gel cushion when in a chair
- E. Reposition the client at least Q 3 hr while in bed
Correct Answer: A, D
Rationale: The correct interventions (A and D) are crucial for preventing pressure ulcers in older adults. Elevating the head of the bed at 30 degrees helps reduce pressure on the sacrum and heels, key areas prone to pressure ulcers. Sitting on a gel cushion distributes pressure evenly, reducing the risk of skin breakdown.
Incorrect Choices:
B: Massaging bony prominences can increase friction and shear forces, leading to skin breakdown.
C: Cornstarch can create a moist environment, increasing the risk of maceration and skin breakdown.
E: Repositioning every 3 hours is insufficient for preventing pressure ulcers, as more frequent repositioning is needed to reduce prolonged pressure on the skin.
