PN ATI Capstone Proctored Comprehensive Assessment B Quizlet
1. A nurse is reviewing laboratory results for a client who has chronic kidney disease. Which of the following findings should the nurse expect?
- A. Hypernatremia
- B. Hypocalcemia
- C. Low potassium
- D. Low magnesium
Correct answer: B
Rationale: In chronic kidney disease, the kidneys have impaired ability to activate vitamin D, leading to decreased production of calcitriol. Calcitriol is essential for calcium absorption in the intestines. Therefore, hypocalcemia is a common finding in chronic kidney disease. Hypernatremia (increased sodium levels) is not typically associated with chronic kidney disease. Low potassium and low magnesium are possible electrolyte imbalances in chronic kidney disease, but they are not as directly related to the impaired activation of vitamin D as hypocalcemia.
2. A nurse in an emergency department is serving on a committee that is reviewing the facility protocol for disaster readiness. The nurse should recommend that the protocol include which of the following as a clinical manifestation of smallpox?
- A. Bloody diarrhea
- B. Ptosis of the eyelids
- C. Descending paralysis
- D. Rash in the mouth
Correct answer: D
Rationale: The correct answer is D, 'Rash in the mouth.' Smallpox presents with a distinctive rash that typically begins in the mouth and spreads to the rest of the body, developing into pustules. This rash is a key clinical manifestation of smallpox. This infectious disease is characterized by the rash, fever, and other systemic symptoms. Choices A, B, and C are incorrect because they are not associated with smallpox. Bloody diarrhea, ptosis of the eyelids, and descending paralysis are not typical clinical manifestations of smallpox.
3. During a skin assessment on a client with risk factors for skin cancer, a nurse should understand that a suspicious lesion is:
- A. Scaly and red
- B. Asymmetric with variegated coloring
- C. Firm and rubbery
- D. Brown with a wart-like texture
Correct answer: B
Rationale: The correct answer is B: Asymmetric with variegated coloring. An asymmetric lesion with variegated coloring, meaning different shades of color within the same lesion, is characteristic of melanoma, a type of skin cancer. This type of lesion should raise suspicions and prompt further evaluation. Choices A, C, and D do not typically represent characteristics of suspicious skin lesions associated with skin cancer. Lesions that are scaly and red (Choice A) may indicate other skin conditions like eczema or psoriasis. Firm and rubbery lesions (Choice C) are more suggestive of benign skin growths like dermatofibromas. Lesions that are brown with a wart-like texture (Choice D) are often indicative of seborrheic keratosis, a benign growth, rather than a suspicious lesion related to skin cancer.
4. A nurse is caring for a client who has peptic ulcer disease (PUD) and is prescribed sucralfate. Which of the following instructions should the nurse include in the teaching?
- A. Take sucralfate with an antacid.
- B. Take sucralfate 1 hour before meals.
- C. Take sucralfate with food.
- D. Take sucralfate at bedtime only.
Correct answer: B
Rationale: The correct answer is B. Sucralfate should be taken on an empty stomach, 1 hour before meals. This timing allows sucralfate to form a protective barrier over the ulcer, enhancing healing. Choice A is incorrect because sucralfate should not be taken with an antacid. Choice C is incorrect because sucralfate should not be taken with food. Choice D is incorrect because sucralfate should not be taken at bedtime only; it is best absorbed on an empty stomach.
5. A nurse is caring for a client who is receiving total parenteral nutrition (TPN). Which of the following assessment findings requires immediate intervention by the nurse?
- A. Prealbumin level of 20 mg/dL
- B. Weight increase of 2 kg/day
- C. Temperature of 37.6°C
- D. Blood glucose level of 120 mg/dL
Correct answer: B
Rationale: A rapid weight gain of 2 kg/day suggests fluid overload, a possible complication of TPN. This requires immediate intervention to prevent further complications such as pulmonary edema. The other options are not indicative of immediate complications related to TPN. A low prealbumin level may indicate malnutrition but does not require immediate intervention. A slightly elevated temperature and blood glucose level are within normal ranges and do not warrant immediate action.
