1. Round off these numbers to the nearest tenth:

A. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7
B. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7
C. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7
D. 5.5778 = 5.6, 1.027 = 1.0, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7

Correct answer: B

Rationale: The correct answer is B. When rounding off to the nearest tenth, 1.027 becomes 1.0 because the digit in the hundredth's place is less than 5. For the other numbers, they are rounded correctly to the nearest tenth: 5.5778 = 5.6, 62.999 = 63, 55.123 = 55.1, 96.676 = 96.7. Therefore, option B is the most accurate in rounding off these numbers to the nearest tenth. Choices A, C, and D are incorrect as they do not round 1.027 to 1.0 as required when rounding to the nearest tenth.

2. A nurse is assessing a client who is postoperative following a left leg below-the-knee amputation. Which of the following client statements indicates the potential need for a referral to an occupational therapist?

A. I hope I can adjust to using crutches while I am recovering.
B. I am worried about taking care of my toddler at home.
C. I just don't think I can handle looking at my leg.
D. I am not sure how I will pay for all the therapy I will need.

Correct answer: A

Rationale: The client's statement about adjusting to using crutches while recovering suggests a potential need for occupational therapy referral. Occupational therapists assist individuals in regaining independence in activities of daily living, including mobility aids and adaptations. Choices B, C, and D are more indicative of emotional or financial concerns and may require referrals to other healthcare professionals like counselors or financial advisors, rather than occupational therapists.

3. A client is in DKA, secondary to infection. As the condition progresses, which of the following symptoms might the nurse see?

A. Kussmaul's respirations and a fruity odor on the breath
B. Shallow respirations and severe abdominal pain
C. Decreased respirations and increased urine output
D. Cheyne-Stokes respirations and foul-smelling urine

Correct answer: A

Rationale: In diabetic ketoacidosis (DKA), as the condition progresses, the body tries to compensate for the acidic environment by increasing the respiratory rate, leading to Kussmaul's respirations. The accumulation of ketones in the body causes a fruity odor on the breath. Option A is correct because Kussmaul's respirations and a fruity odor on the breath are classic signs of DKA. Option B is incorrect because shallow respirations are not typically seen in DKA, and severe abdominal pain is more commonly associated with conditions like pancreatitis. Option C is incorrect as decreased respirations are not a typical finding in DKA, and increased urine output is more commonly seen in conditions like diabetes insipidus. Option D is incorrect because Cheyne-Stokes respirations are not characteristic of DKA, and foul-smelling urine is not a prominent symptom in this condition.

4. Dr. Shrunk orders intravenous (IV) insulin for Rita, a client with a blood sugar of 563. Nurse AJ administers insulin lispro (Humalog) intravenously (IV). What does the best evaluation of the nurse reveal? Select one that does not apply.

A. The nurse could have given the insulin subcutaneously.
B. The nurse did not have to contact the physician.
C. The nurse should have used regular insulin (Humulin R).
D. The nurse used the correct insulin.

Correct answer: C

Rationale: The best evaluation of the nurse reveals that she should have used regular insulin (Humulin R) for IV administration. Regular insulin is the only insulin approved for intravenous administration due to its pharmacokinetic properties. Insulin lispro (Humalog) is not suitable for IV use. Choice A is incorrect because giving insulin intravenously is necessary in this case of high blood sugar. Choice B is incorrect because administering a different insulin without consulting the physician is not appropriate. Choice D is incorrect because the nurse used the incorrect insulin, which could pose risks to the client's health.

5. What is an episiotomy?

A. A surgical incision of the perineum to prevent tearing during delivery.
B. Releasing the red plug from the cervix just before crowning occurs.
C. An incision in the abdomen with which the baby can be delivered through.
D. The severance of the umbilical cord between mother and child.

Correct answer: A

Rationale: An episiotomy is a surgical incision of the perineum to prevent tearing during delivery. This procedure is performed to widen the vaginal opening and facilitate childbirth. Choice B is incorrect as it describes the expulsion of the mucus plug, not an episiotomy. Choice C is incorrect as it refers to a different procedure, a cesarean section, where the baby is delivered through an incision in the abdomen. Choice D is incorrect as it pertains to cutting the umbilical cord, which is not related to an episiotomy.
