1. The nurse is teaching parents of a newborn about feeding their infant. Which of the following instructions should the nurse include?
- A. Use the defrost setting on microwave ovens to warm bottles.
- B. When refrigerating formula, discard partially used bottles after 24 hours.
- C. When using formula concentrate, mix one part water and one part concentrate.
- D. When using powdered formula, mix two parts water and one part powder.
Correct answer: A
Rationale: The correct answer is to use the defrost setting on microwave ovens to warm bottles. It is essential for parents to be cautious when warming bottles in a microwave oven to prevent superheating of the milk. Choosing the defrost setting and checking the formula temperature before giving it to the baby helps avoid burns. Discarding partially used bottles after 24 hours when refrigerating formula is crucial as it reduces the risk of harmful bacterial growth. Mixing formula concentrate with water in a 1:1 ratio of one part concentrate to one part water ensures proper dilution of the formula. On the other hand, powdered formula should be mixed following the package instructions, typically using two parts water to one part powder. This accurate mixing ratio provides the necessary balance of nutrients for the baby. Adding fresh formula to partially used bottles can introduce pathogens that may harm the infant, underscoring the importance of discarding partially used bottles and preparing formula correctly. Therefore, options B, C, and D are incorrect as they do not address the safe and proper ways to feed a newborn effectively.
2. A nurse in the healthcare provider's office is checking the Babinski reflex in a 3-month-old infant. The nurse determines that the infant's response is normal if which finding is noted?
- A. The fingers curl tightly, and the toes curl forward.
- B. The toes flare, and the big toe is dorsiflexed.
- C. There is extension of the extremities on the side to which the head is turned, with flexion on the opposite side.
- D. The infant turns to the side that is touched.
Correct answer: B
Rationale: To elicit the Babinski reflex, the nurse strokes the lateral sole of the foot from the heel to across the base of the toes. In the expected response, the toes flare, and the big toe dorsiflexes. The Babinski reflex disappears at 12 months of age. Turning to the side that is touched is the expected response when the rooting reflex is elicited. Tight curling of the fingers and forward curling of the toes is the expected response when the grasp reflex (palmar and plantar) is elicited. Extension of the extremities on the side to which the head is turned with flexion on the opposite side is the expected response when the tonic neck reflex is elicited.
3. A nurse is preparing to auscultate a fetal heart rate (FHR). The nurse performs the Leopold maneuvers to determine the position of the fetus and then places the fetoscope over which part of the fetus?
- A. Back of the fetus
- B. Carotid artery in the neck of the fetus
- C. Brachial area of one extremity of the fetus
- D. Chest of the fetus
Correct answer: A
Rationale: The nurse would use the Leopold maneuvers to identify the position of the fetus and determine the location of the fetal back. The fetal heart rate (FHR) is most easily heard through the fetal back because it usually lies closest to the surface of the maternal abdomen. Auscultation of the FHR over the chest, carotid artery, or brachial area is not possible due to the fetal position within the maternal abdomen. Placing the fetoscope over the carotid artery or brachial area would not yield the fetal heart rate, and the chest area is not typically used for auscultating the FHR.
4. An allergic reaction is classified as what type of pharmacological effect?
- A. a therapeutic effect
- B. a side effect
- C. an adverse effect
- D. an incompatibility
Correct answer: C
Rationale: An allergic reaction is classified as an adverse effect because it is an unintended response to a medication that requires treatment. A side effect is an undesired but somewhat expected reaction to a drug that does not necessarily need intervention. Incompatibility refers to an unsuitable combination of substances that leads to an adverse effect. A therapeutic effect is the desired and intended outcome of a medication.
5. A nurse is preparing to assist the healthcare provider in performing an internal gynecological examination of a client. In which position does the nurse place the client for this examination?
- A. Prone
- B. Left side-lying
- C. Sims
- D. Lithotomy
Correct answer: D
Rationale: An internal gynecological examination is performed with the client in the lithotomy position. In this position, the client is supine, with the feet in stirrups, the knees apart, and the buttocks at the end of the examining table. The client is draped so that only the vulva is exposed. The lithotomy position provides optimal access for the healthcare provider to perform the examination effectively. The prone position refers to lying on the stomach, which is not suitable for a gynecological exam. The Sims position is a left side-lying position primarily used for administering enemas, not for gynecological examinations.
