ATI Nutrition Proctored Exam 2019 Answers
1. Infections are common in people who have inadequate protein intake because of an insufficient quantity of:
- A. insulin.
- B. lipoprotein.
- C. antibodies.
- D. albumin.
Correct answer: C
Rationale: Inadequate protein intake can lead to a decrease in antibody production, making individuals more susceptible to infections. Insulin (Choice A) is a hormone involved in regulating blood sugar levels, not related to protein intake. Lipoprotein (Choice B) is a type of lipid-protein complex involved in lipid transport, not directly related to antibody production. Albumin (Choice D) is a protein that helps maintain oncotic pressure and carries various substances in the blood, but it is not primarily responsible for fighting infections like antibodies.
2. A client is prescribed digoxin for heart failure. Which of the following should the nurse monitor to evaluate the effectiveness of the medication?
- A. Respiratory rate
- B. Blood pressure
- C. Apical pulse
- D. Urine output
Correct answer: C
Rationale: The correct answer is C: Apical pulse. Digoxin's primary effect is to strengthen the force of the heart's contractions and slow the heart rate. Monitoring the apical pulse is crucial in evaluating the effectiveness of digoxin as it helps assess the medication's impact on the heart's function. Option A, respiratory rate, is not directly related to digoxin's mechanism of action and is not the most appropriate parameter to monitor for this medication. Option B, blood pressure, while important, may not be as sensitive as the apical pulse in assessing the effectiveness of digoxin. Option D, urine output, is more indicative of kidney function and fluid balance, rather than the direct effectiveness of digoxin in heart failure.
3. A nurse is preparing to administer heparin 8,000 units subcutaneously every eight hours. The amount available is heparin injection 10,000 units/mL. How many milliliters should the nurse administer per dose? (Round the answer to the nearest tenth)
- A. 0.8 mL
- B. 0.9 mL
- C. 10.0 mL
- D. 98.0 mL
Correct answer: A
Rationale: To determine the volume of heparin to administer per dose, divide the prescribed dose (8,000 units) by the concentration of heparin available (10,000 units/mL). 8000 units / 10000 units/mL = 0.8 mL. Therefore, the nurse should administer 0.8 mL per dose. Choice B, 0.9 mL, is incorrect as the correct calculation results in 0.8 mL. Choices C and D are significantly higher and incorrect, indicating an inaccurate calculation.
4. The nurse is assessing a postpartum client's fundus. Where should the nurse expect to find the fundus 24 hours after delivery?
- A. At the level of the umbilicus
- B. 1 cm above the symphysis pubis
- C. At the level of the xiphoid process
- D. 2 cm below the umbilicus
Correct answer: A
Rationale: After delivery, the fundus is expected to be at the level of the umbilicus 24 hours postpartum. This position indicates that the uterus is involuting properly. Assessing the fundal height helps monitor the progress of uterine involution and can identify any potential complications like postpartum hemorrhage.
5. A client is on a mechanical ventilator. Which client response indicates that the neuromuscular blocker tubocurarine chloride (Tubarine) is effective?
- A. The client's extremities are paralyzed.
- B. The peripheral nerve stimulator causes twitching.
- C. The client clenches fist upon command.
- D. The client's Glasgow Coma Scale score is 14.
Correct answer: A
Rationale: The correct answer is A. Tubocurarine chloride is a neuromuscular blocker that works by causing paralysis of skeletal muscles. Therefore, if the client's extremities are paralyzed, it indicates that the medication is effective in achieving the desired muscle relaxation necessary for mechanical ventilation. Choices B and C are incorrect as they suggest muscle activity, which would not be expected with the administration of a neuromuscular blocker. Choice D is unrelated to the effectiveness of tubocurarine chloride.
