1. Which deficiency in the mother has been primarily associated with neural tube defects in the fetus?
- A. Iron
- B. Folic acid
- C. Vitamin B12
- D. Vitamin E
Correct answer: B
Rationale: Folic acid deficiency in the mother has been primarily associated with neural tube defects in the fetus. Folic acid is crucial for the development of the neural tube in the early stages of pregnancy. Its deficiency can lead to neural tube defects, such as spina bifida or anencephaly. Iron deficiency is not directly related to neural tube defects but can cause other complications in pregnancy. Vitamin B12 is important for neurological function but is not the primary cause of neural tube defects. Vitamin E deficiency is not associated with neural tube defects in the fetus.
2. A patient has been prescribed Tegretol for the first time. Which of the following side effects is not associated with Tegretol?
- A. Sore throat
- B. Vertigo
- C. Fever
- D. Shortness of breath
Correct answer: D
Rationale: The correct answer is 'Shortness of breath.' Side effects commonly associated with Tegretol include sore throat, vertigo, and fever. Shortness of breath is not a typical side effect of Tegretol use. Sore throat, vertigo, and fever are known side effects of Tegretol, while shortness of breath is not typically linked to its use.
3. A mother who has never breastfed a child before is having trouble getting the baby to latch on to the breast. The baby has lost 3% of its birth weight within the first 2 days of life. The best statement is:
- A. The baby will eventually take to the breast.
- B. I can prepare a bottle if you want to try that.
- C. A small amount of weight loss in the first few days is normal.
- D. I can arrange for the charge nurse to come and talk to you about breastfeeding.
Correct answer: C
Rationale: The correct answer is 'A small amount of weight loss in the first few days is normal.' It is important to reassure the mother that a small amount of weight loss, such as 5-10% of birth weight, in the first few days of life is considered normal for newborns. This reassurance helps alleviate the mother's concerns. Option A is incorrect because it does not address the concern about weight loss; it focuses more on the baby eventually latching on. Option B is not recommended as the first solution for breastfeeding issues, as introducing a bottle early on may lead to nipple confusion. Option D involves escalating the situation to the charge nurse when it can be addressed by providing appropriate information and support directly, making it less necessary in this scenario where reassurance and education are key.
4. Levothyroxine (Synthroid) is the drug of choice for thyroid replacement therapy in clients with hypothyroidism because:
- A. it is chemically stable, nonallergenic, and can be administered orally once a day.
- B. it is available in a wide range of concentrations to meet individual client requirements.
- C. it is a prodrug of T3.
- D. it has a long half-life.
Correct answer: A
Rationale: Levothyroxine (Synthroid) is the preferred medication for hypothyroidism due to its chemical stability, nonallergenic properties, and convenient once-daily oral administration. It is safe and effective with minimal side effects when appropriately dosed. Choice B is incorrect because while Levothyroxine is available in various concentrations, it is not the reason it is the drug of choice; the primary reason is its stability and nonallergenic nature. Choice C is wrong as Levothyroxine (T4) is not a prodrug of T3; it is converted to T3 in the body. Option D is inaccurate because Levothyroxine has a long half-life (around 7 days), enabling once-daily dosing, as opposed to a short half-life.
5. A healthcare professional is reviewing a patient's ECG report. The patient exhibits a flat T wave, depressed ST segment, and short QT interval. Which of the following medications can cause all of the above effects?
- A. Morphine
- B. Atropine
- C. Procardia
- D. Digitalis
Correct answer: D
Rationale: The correct answer is Digitalis. Digitalis is known to cause a flat T wave, depressed ST segment, and a short QT interval on an ECG report. These ECG changes are characteristic of digitalis toxicity. Morphine is not typically associated with these ECG changes. Atropine is more commonly linked to increasing heart rate rather than causing these specific ECG abnormalities. Procardia is a calcium channel blocker that does not typically produce the described ECG findings. Therefore, Digitalis is the most likely medication causing these effects in the patient.
