1. A patient with peptic ulcer disease is prescribed omeprazole. When should the patient take this medication for optimal effectiveness?
- A. With meals
- B. At bedtime
- C. Before meals
- D. After meals
Correct answer: C
Rationale: Omeprazole should be taken before meals to reduce stomach acid production and promote healing of the ulcer. Taking it before meals ensures that the medication can inhibit acid secretion when the stomach is most active in producing acid, thereby maximizing its effectiveness in treating peptic ulcer disease.
2. A client with pregestational type 1 diabetes mellitus is being taught by a nurse about management during pregnancy. Which of the following statements by the client indicates an understanding of the teaching?
- A. I should aim to maintain my fasting blood glucose between 100 and 120.
- B. I should engage in moderate exercise for 30 minutes if my blood glucose is 250 or higher.
- C. I will continue taking my insulin if I experience nausea and vomiting.
- D. I will avoid exercise if my blood glucose exceeds 250.
Correct answer: C
Rationale: The correct answer is C. It is essential for a client with pregestational type 1 diabetes mellitus to continue taking insulin as prescribed even if they experience nausea and vomiting. This is crucial to prevent fluctuations in blood glucose levels that could lead to serious complications. Choice A is incorrect because the fasting blood glucose target for pregnant women with diabetes is usually lower. Choice B is incorrect as engaging in exercise when blood glucose is high is not recommended. Choice D is incorrect as avoiding exercise is not the appropriate approach when blood glucose levels are elevated.
3. A client is newly diagnosed with hypothyroidism and prescribed levothyroxine. Which of the following instructions should the nurse include?
- A. Take the medication with food.
- B. Take the medication in the evening.
- C. Take the medication on an empty stomach.
- D. Take the medication only when experiencing symptoms.
Correct answer: C
Rationale: The correct instruction is to take levothyroxine on an empty stomach. This is necessary for proper absorption and effectiveness of the medication. Taking it with food can interfere with absorption. Timing is also crucial; it is usually recommended to take levothyroxine in the morning to prevent potential interactions with food and other medications throughout the day. Taking the medication in the evening may lead to sleep disturbances. Lastly, waiting to take the medication only when symptoms occur is not appropriate as levothyroxine is typically taken regularly to maintain thyroid hormone levels within the body.
4. What percentage of total body surface area has been burned in a 5-year-old child who experienced partial-thickness burns to his head, anterior chest, and both upper extremities?
- A. 45%
- B. 63%
- C. 72%
- D. 54%
Correct answer: A
Rationale: According to the pediatric rule of nines, the head and neck represent 18%, the anterior chest and abdomen 18%, and each arm 9%. By adding these percentages (18% + 18% + 9% + 9% = 45%), we find that 45% of the total body surface area has been burned in this child.
5. A 60-year-old man presents with fatigue, weight gain, and constipation. Laboratory tests reveal low TSH and high free T4 levels. What is the most likely diagnosis?
- A. Hypothyroidism
- B. Hyperthyroidism
- C. Thyroiditis
- D. Thyroid cancer
Correct answer: B
Rationale: The combination of low TSH and high free T4 levels is characteristic of hyperthyroidism, not hypothyroidism. Hyperthyroidism is associated with symptoms such as fatigue, weight loss, and diarrhea, contrasting with the typical presentation of hypothyroidism. Therefore, in this case, the most likely diagnosis is hyperthyroidism.
