HESI RN
HESI 799 RN Exit Exam Capstone
1. The nurse administers an antibiotic for a respiratory tract infection. To evaluate the medication's effectiveness, which laboratory values should the nurse monitor?
- A. Platelet count and red blood cell count.
- B. White blood cell count and sputum culture.
- C. Hemoglobin A1c and glucose tolerance test.
- D. Arterial blood gases and serum electrolytes.
Correct answer: B
Rationale: The correct answer is B: White blood cell count and sputum culture. Monitoring white blood cell count and sputum cultures is essential to assess the effectiveness of the antibiotic in treating the respiratory tract infection. Changes in white blood cell count can indicate the body's response to infection, while sputum cultures help determine if the antibiotic is targeting the specific pathogens causing the infection. Choices A, C, and D are incorrect because platelet count, red blood cell count, hemoglobin A1c, glucose tolerance test, arterial blood gases, and serum electrolytes are not directly related to evaluating the effectiveness of an antibiotic in treating a respiratory tract infection.
2. A client with severe dehydration is admitted to the hospital. Which assessment finding indicates that the client's condition is improving?
- A. The client reports feeling less thirsty
- B. Urine output increases to 40 mL/hour
- C. Heart rate decreases from 120 to 110 beats per minute
- D. Skin turgor returns to normal
Correct answer: B
Rationale: An increase in urine output is a reliable indicator that the client's hydration status is improving. This reflects adequate fluid replacement and improved kidney function. Choice A is subjective and may not always indicate improved hydration. Choice C, while a positive sign, may be influenced by other factors such as medications or pain. Choice D, skin turgor returning to normal, is a delayed indicator of hydration status and may take time to improve even after hydration is initiated.
3. When assessing a male client with pheochromocytoma, a tumor of the adrenal medulla that secretes excessive catecholamines, Nurse April is most likely to detect:
- A. A blood pressure of 130/70 mm Hg
- B. A blood glucose level of 130 mg/dl
- C. Bradycardia
- D. A blood pressure of 176/88 mm Hg
Correct answer: D
Rationale: Pheochromocytoma is a tumor of the adrenal medulla that secretes excessive catecholamines, leading to symptoms such as hypertension. The normal blood pressure range is around 120/80 mm Hg, so a blood pressure reading of 176/88 mm Hg is most likely to be detected in a client with pheochromocytoma. Choices A, B, and C are incorrect because pheochromocytoma typically presents with hypertension, not a normal or low blood pressure (choice A), not related to blood glucose levels (choice B), and not bradycardia (choice C).
4. What is the most significant contributor to cellular function?
- A. Proteins
- B. Phospholipids
- C. Carbohydrates
- D. Fatty acids
Correct answer: A
Rationale: The correct answer is A: Proteins. Proteins are the most significant contributor to cellular function as they play crucial roles in almost all biological processes. They act as enzymes that catalyze reactions, are involved in cell signaling pathways, and provide structural support to cells. Phospholipids (Choice B), while important for cell membrane structure, do not have the same diverse functions as proteins in cellular processes. Carbohydrates (Choice C) primarily serve as an energy source and structural components but are not as versatile in cellular functions as proteins. Fatty acids (Choice D) are essential components of cell membranes and energy storage molecules but do not have the same broad range of functions as proteins in cellular processes.
5. A nurse is teaching a client with type 2 diabetes about the importance of foot care. Which statement by the client indicates a need for further teaching?
- A. I should check my feet every day for cuts or blisters.
- B. I need to moisturize my feet daily, especially between my toes.
- C. I should wear comfortable shoes that fit well.
- D. I should avoid walking barefoot, even indoors.
Correct answer: B
Rationale: The correct answer is B. Moisturizing between the toes can create a moist environment that fosters fungal infections. Checking the feet daily for cuts or blisters (choice A) is correct in diabetes management to prevent complications. Wearing comfortable shoes that fit well (choice C) and avoiding walking barefoot (choice D) are also essential in preventing foot ulcers and injuries in diabetic patients.
