RN ATI Capstone Proctored Comprehensive Assessment 2019 B with NGN
1. A nurse is assessing a client who has asthma. Which of the following areas should the nurse evaluate as the most reliable indicator of central cyanosis?
- A. Oral mucosa
- B. Conjunctivae
- C. Soles of the feet
- D. Ear lobes
Correct answer: A
Rationale: Central cyanosis is best assessed by examining the oral mucosa, as it is a more reliable indicator compared to other areas like the conjunctivae, soles of the feet, and ear lobes. The oral mucosa reflects the oxygen saturation levels of the blood more accurately. Conjunctivae and ear lobes may show cyanosis, but they are not as reliable as the oral mucosa. The soles of the feet are not typically used to assess central cyanosis.
2. A healthcare professional is planning care for a client who is scheduled for a lumbar puncture. Which of the following actions should the healthcare professional include?
- A. Restrict the client's fluid intake for 4 hours following the procedure
- B. Apply cold compresses to the puncture site after the procedure
- C. Instruct the client to increase oral fluid intake after the procedure
- D. Keep the client in a prone position for 12 hours after the procedure
Correct answer: C
Rationale: The correct action to include in caring for a client scheduled for a lumbar puncture is to instruct the client to increase oral fluid intake after the procedure. Increasing oral fluid intake helps replace cerebrospinal fluid lost during the lumbar puncture and reduces the risk of headaches. Restricting fluid intake (Choice A) is not recommended as it can lead to dehydration. Applying cold compresses (Choice B) is not necessary after a lumbar puncture. Keeping the client in a prone position for 12 hours (Choice D) is not required after a lumbar puncture and can cause discomfort and complications.
3. A nurse is preparing to measure a client's level of oxygen saturation and observes edema of both hands and thickened toenails. The nurse should apply the pulse oximeter probe to which of the following locations?
- A. Finger
- B. Earlobe
- C. Toe
- D. Skin fold
Correct answer: B
Rationale: When a client has edema of both hands and thickened toenails, these conditions can impede accurate readings from the finger and toe locations. The earlobe is the best alternative site for the pulse oximeter probe in this scenario. Placing the probe on the earlobe will help ensure a more accurate measurement of oxygen saturation despite the issues with the hands and toenails. Therefore, the correct answer is to apply the pulse oximeter probe to the earlobe. Choices A, C, and D are incorrect because of the potential limitations presented by the edema and thickened toenails.
4. A patient is being treated for dehydration. Which lab result would support the diagnosis?
- A. Elevated hemoglobin
- B. Low sodium level
- C. High white blood cell count
- D. Elevated BUN
Correct answer: D
Rationale: Elevated BUN levels are a characteristic finding in dehydration due to reduced kidney perfusion and increased reabsorption of urea. Hemoglobin levels might be elevated in conditions like polycythemia vera, not directly related to dehydration. A low sodium level could be seen in conditions like hyponatremia. A high white blood cell count is more indicative of infection or inflammation rather than dehydration.
5. When administering an IM injection into a client's deltoid muscle, which of the following actions should the nurse take?
- A. Use a 21-gauge needle for the injection
- B. Inject the medication at a 90-degree angle
- C. Inject the medication 12.7 cm (5 in) below the acromion process
- D. Inject the medication 2.54 cm (1 in) below the acromion process
Correct answer: B
Rationale: The correct answer is to inject the medication at a 90-degree angle when administering an IM injection into the deltoid muscle. This angle ensures proper delivery of the medication into the muscle tissue. Choice A is incorrect because the gauge of the needle for a deltoid IM injection is usually smaller, around 23-25 gauge. Choices C and D are incorrect as the injection site for the deltoid muscle is approximately 2.54 cm (1 in) below the acromion process, not 12.7 cm (5 in).
