The dosage of a pediatric medication is 120mg/kg/day to be given t.i.d. The patient weighs 12 pounds. What is the correct dose for the nurse to administer?
- A. 120 mg
- B. 480 mg
- C. 218 mg
- D. 651 mg
Correct Answer: C
Rationale: The patient weighs twelve pounds, which converts to kilograms by dividing 12 by 2.2 (1 kg = 2.2 lb.). In this example, the child's weight converts to 5.4 kg. The daily dose of 120 mg is given t.i.d: each individual dose is 40 mg/kg. Then multiply the weight in kilograms by the individual dose (40mg). The individual dose is 218 mg.

A multiparous woman with a history of all vaginal births is admitted to the hospital in labor. After several hours, the client's labor has not progressed and she is getting tired and restless. The decision is made to proceed with cesarean delivery. The nurse recognizes the client's knowledge deficit regarding the surgical delivery and care after birth. Which is the appropriate expected outcome for correction of the client's knowledge deficit? The client will:
- A. Demonstrate appropriate coping mechanisms needed to get through the surgery.
- B. Accept that the type of delivery will not affect the bonding with the baby.
- C. Verbalize understanding about the reason for the unplanned surgery.
- D. Demonstrate decreased anxiety and fear of the unknown.
Correct Answer: C
Rationale: The correct answer is C: Verbalize understanding about the reason for the unplanned surgery. This outcome focuses on the client understanding why the cesarean delivery is necessary, which is crucial for informed decision-making and reducing anxiety. It shows the client comprehends the situation, which is important for her emotional well-being and cooperation during the procedure and postpartum period. Option A is incorrect because coping mechanisms are important but not directly related to knowledge deficit correction. Option B is incorrect as it does not address the client's knowledge deficit but rather focuses on emotional aspects. Option D is incorrect as it addresses anxiety and fear but not the underlying issue of knowledge deficit.
A nurse is collecting data on a 3-year-old child with eczema in an outpatient center.
- A. "Cover the crib mattress with a plastic cover."'
- B. "Give the child a bubble bath for 20 min each day."'
- C. "Place a humidifier in the child's room."'
- D. "Dress the child in warm wool clothing in cold weather."'
Correct Answer: C
Rationale: The correct answer is C, "Place a humidifier in the child's room." This is because eczema can worsen with dry skin, and a humidifier can help maintain moisture in the air, preventing skin dryness. Choice A is incorrect as a plastic cover can trap heat and sweat, exacerbating eczema. Choice B is incorrect as bubble baths can irritate sensitive skin. Choice D is incorrect as wool clothing can be abrasive and trigger eczema flare-ups.
A nurse is caring for a 7-year-old child who is admitted with an asthma exacerbation.
- A. "Monitoring oxygen saturation and respiratory rate daily."'
- B. "Identification and avoidance of factors that trigger symptoms."'
- C. "Monitoring peak flow measurements regularly."'
- D. "Positioning the client upright in a position of comfort."'
Correct Answer: B
Rationale: The correct answer is B because identifying and avoiding triggers helps prevent asthma exacerbations. This proactive approach addresses the root cause of the issue, promoting long-term management. Monitoring oxygen saturation, respiratory rate, and peak flow are important but reactive measures, not addressing the underlying triggers. Positioning upright aids breathing but does not prevent exacerbations.
A client at 33 weeks gestation is admitted for suspected abruptio placenta. Which factor in the client's history supports this diagnosis? The client states that she:
- A. drinks two glasses of wine before dinner every night.
- B. has intermittent contractions that are relieved by walking.
- C. had intercourse with her partner last night.
- D. used crack an hour before the symptoms began.
Correct Answer: D
Rationale: The correct answer is D: used crack an hour before the symptoms began. Abruptio placenta is a condition where the placenta prematurely separates from the uterine wall. Substance abuse, such as crack cocaine, can lead to vasoconstriction and increased risk of abruptio placenta due to compromised blood flow to the placenta. This can result in fetal distress and maternal bleeding. The other choices (A, B, C) do not directly correlate with abruptio placenta. Intermittent contractions relieved by walking are more suggestive of Braxton Hicks contractions, intercourse is not a known risk factor for abruptio placenta, and drinking wine does not typically cause this condition.
A client asks the nurse about the benefits of breastfeeding. Which response by the nurse provides the most accurate information?
- A. Breastfeeding helps women lose weight faster.
- B. Breast milk contains a greater amount of protein.
- C. Breast milk is easier to digest than formula.
- D. Breastfeeding is a good method of contraception.
Correct Answer: C
Rationale: The correct answer is C: Breast milk is easier to digest than formula. Breast milk contains specific enzymes and antibodies that aid in digestion and are easily absorbed by the baby's immature digestive system. This promotes better nutrient absorption and reduces the risk of digestive issues. Option A is incorrect because weight loss varies for each woman and should not be the primary reason for breastfeeding. Option B is incorrect as breast milk has a balanced composition of nutrients, not just higher protein content. Option D is incorrect as breastfeeding is not a reliable form of contraception.
