A nurse is preparing to administer metronidazole 2 g PO to a client who has trichomoniasis. Available is metronidazole 250 mg tablets. How many tablets should the nurse administer?
- A. 8 tablets
- B. 4 Tablets
- C. 2 tablets
- D. 1 tablet
Correct Answer: A
Rationale: The correct answer is A: 8 tablets. To calculate the correct dosage, divide the total dose by the dose per tablet. In this case, 2 g = 2000 mg, and each tablet is 250 mg. Therefore, 2000 mg ÷ 250 mg = 8 tablets. This ensures the client receives the correct dosage for effective treatment. Choice B (4 tablets) would result in an underdose, C (2 tablets) would be half the required dose, and D (1 tablet) would be significantly lower than the needed dose, leading to ineffective treatment.

- A. Allocation of resources
- B. Withholding or withdrawing life-sustaining treatment
- C. Use of alternative therapies without informed consent

A nurse is providing teaching about increasing dietary fiber to an antepartum client who reports constipation. Which of the following food selections has the highest fiber content per cup?
- A. Oatmeal
- B. Cabbage
- C. Asparagus
- D. Lentils
Correct Answer: D
Rationale: The correct answer is D: Lentils. Lentils have the highest fiber content per cup compared to the other options. Lentils contain around 15.6 grams of fiber per cup, making them an excellent choice to alleviate constipation. Oatmeal, cabbage, and asparagus have lower fiber content per cup compared to lentils. Oatmeal contains around 4 grams of fiber per cup, cabbage has about 2.2 grams, and asparagus has approximately 2.8 grams. Therefore, lentils are the best choice for increasing fiber intake to help with constipation during pregnancy.
A nurse is caring for a client who is at 10 weeks of gestation. Which of the following findings should the nurse report to the provider?
- A. Frequent vomiting with weight loss of 3 lb in 1 week
- B. Reports of mood swings
- C. Nosebleeds occurring approximately 3 times per week
- D. Increased vaginal discharge
Correct Answer: A
Rationale: The correct answer is A. Frequent vomiting with weight loss of 3 lb in 1 week is concerning during the first trimester as it may indicate hyperemesis gravidarum, a severe form of morning sickness that can lead to dehydration and malnutrition, posing risks to both the mother and the fetus. The nurse should report this finding to the provider for further evaluation and intervention.
Incorrect choices:
B: Reports of mood swings are common during pregnancy due to hormonal changes and are not typically a cause for concern at 10 weeks of gestation.
C: Nosebleeds are common in pregnancy due to increased blood volume and hormonal changes and are usually not serious unless severe or frequent.
D: Increased vaginal discharge is a normal pregnancy symptom caused by hormonal changes and increased blood flow to the pelvic area.
What is the recommended method of feeding for a preterm infant?
- A. Breastfeeding
- B. Formula feeding
- C. Bottle feeding with breast milk
- D. Parenteral nutrition
Correct Answer: C
Rationale: The correct answer is C: Bottle feeding with breast milk. Preterm infants may have difficulty latching onto the breast due to their immature sucking reflex. Bottle feeding with breast milk allows for easier feeding and enables monitoring of intake. Breast milk provides essential nutrients and antibodies crucial for preterm infant development. Formula feeding (B) may lack these benefits. Breastfeeding (A) may be challenging for preterm infants initially. Parenteral nutrition (D) is typically used when a baby cannot tolerate oral feedings.
Which stage of labor is characterized by cervical dilation from 4-10 cm?
- A. First stage
- B. Second stage
- C. Third stage
- D. Fourth stage
Correct Answer: A
Rationale: The correct answer is A: First stage. This stage of labor is characterized by cervical dilation from 4-10 cm. During this stage, the cervix prepares for childbirth by thinning and opening up to allow the baby to pass through the birth canal. The first stage is further divided into early labor (0-4 cm dilation) and active labor (4-10 cm dilation). It is crucial for monitoring progress and determining when to move to the next stage of labor. The other choices are incorrect because the second stage is characterized by pushing and delivery of the baby, the third stage is delivery of the placenta, and the fourth stage is the postpartum period immediately after delivery.
