Nursing Elites

1. A nurse is assessing a client who has diabetic ketoacidosis (DKA). Which of the following laboratory findings should the nurse expect?

• A. Blood glucose 120 mg/dL
• B. pH 7.32
• C. HCO3 25 mEq/L
• D. PaCO2 48 mm Hg

Correct answer: B

Rationale: The correct answer is B. A pH of 7.32 indicates metabolic acidosis, which is a hallmark of diabetic ketoacidosis (DKA). In DKA, blood glucose levels are typically elevated, bicarbonate levels are often low, and there is a compensatory respiratory response leading to a decrease in PaCO2. Option A is incorrect because a blood glucose level of 120 mg/dL is within the normal range and not indicative of DKA. Option C is incorrect because an HCO3 level of 25 mEq/L is not typically seen in DKA where bicarbonate levels are usually lower. Option D is incorrect because a PaCO2 of 48 mm Hg would not be expected in DKA; it would typically be lower due to compensatory respiratory alkalosis.

2. A nurse is caring for a client who has severe preeclampsia and is receiving magnesium sulfate. The nurse should monitor the client for which of the following findings as an indication of magnesium toxicity?

• A. Decreased deep tendon reflexes
• B. Elevated blood pressure
• C. Increased urinary output
• D. Hyperreflexia

Correct answer: A

Rationale: The correct answer is A: Decreased deep tendon reflexes. Magnesium sulfate toxicity can lead to diminished deep tendon reflexes, respiratory depression, and decreased urine output. Diminished deep tendon reflexes are an early sign of magnesium toxicity and indicate the need to discontinue the infusion. Elevated blood pressure (choice B) is not typically associated with magnesium toxicity. Increased urinary output (choice C) is also not a common finding in magnesium toxicity. Hyperreflexia (choice D) is not consistent with the expected findings of magnesium toxicity, which typically causes decreased reflexes.

3. A nurse is performing a focused assessment on a client who has a history of COPD and is experiencing dyspnea. Which of the findings should the nurse expect?

• A. Flaring of the nostrils
• B. Normal respiratory rate
• C. Clear lung sounds
• D. Decreased work of breathing

Correct answer: A

Rationale: Flaring of the nostrils indicates increased respiratory effort, common in clients with dyspnea due to COPD. In COPD, the airways are narrowed, causing difficulty in breathing, leading to increased work of breathing. Normal respiratory rate and clear lung sounds are less likely findings in a client with COPD experiencing dyspnea. Decreased work of breathing is not expected in this situation as COPD typically results in increased work of breathing.

4. A nurse providing dietary teaching for a client who is at 29 weeks of gestation and has phenylketonuria. Which of the following suggested foods should the nurse include in the teaching?

• A. A peanut butter sandwich on wheat bread
• B. A sliced apple and red grapes
• C. A chocolate chip cookie with a glass of skim milk
• D. A scrambled egg with cheddar cheese

Correct answer: B

Rationale: The correct answer is B. Clients with phenylketonuria (PKU) must adhere to a strict low-phenylalanine diet to prevent neurological damage. Foods high in phenylalanine such as peanut butter, wheat bread, chocolate chip cookies, milk, scrambled eggs, and cheddar cheese should be avoided. Sliced apples and red grapes are low in phenylalanine, making them safe choices for individuals with PKU. Choice A (peanut butter sandwich on wheat bread), Choice C (chocolate chip cookie with a glass of skim milk), and Choice D (scrambled egg with cheddar cheese) are all high in phenylalanine and should be avoided by individuals with PKU.

5. 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.
