1. Assessment findings of a 4-hour-old newborn include: axillary temperature of 96.8°F (35.8°C), heart rate of 150 beats/minute with a soft murmur, irregular respiratory rate at 64 breaths/minute, jitteriness, hypotonia, and weak cry. Based on these findings, which action should the nurse implement?
- A. Swaddle the infant in a warm blanket.
- B. Obtain a heel stick blood glucose level.
- C. Place a pulse oximeter on the heel.
- D. Document the findings in the record.
Correct answer: B
Rationale: The assessment findings in the newborn, such as jitteriness, weak cry, and hypotonia, are indicative of potential hypoglycemia. To confirm this suspicion, the nurse should obtain a heel stick blood glucose level, which is the most appropriate action in this situation. Checking the blood glucose level will provide crucial information to determine the newborn's glucose status and guide further management if hypoglycemia is confirmed. Swaddling the infant in a warm blanket does not address the underlying issue of potential hypoglycemia and may not effectively raise the blood glucose level. Placing a pulse oximeter on the heel is not indicated for assessing hypoglycemia. Documenting the findings in the record is important but does not address the immediate concern of assessing and managing potential hypoglycemia.
2. A breastfeeding infant, screened for congenital hypothyroidism, is found to have low levels of thyroxine (T4) and high levels of thyroid-stimulating hormone (TSH). What is the best explanation for this finding?
- A. The thyroxine level is low because the TSH level is high.
- B. High thyroxine levels do not normally occur in breastfeeding infants.
- C. The thyroid gland does not produce normal levels of thyroxine for several weeks after birth.
- D. The TSH is high because of the low production of T4 by the thyroid.
Correct answer: D
Rationale: High TSH and low T4 levels indicate that the thyroid gland is not producing enough hormones, which is a sign of congenital hypothyroidism. In this case, the high TSH is a compensatory response by the body to stimulate the thyroid to produce more T4. Choice A is incorrect because TSH does not directly affect T4 levels; rather, it is the other way around where low T4 levels lead to high TSH levels. Choice B is incorrect because high thyroxine levels are not expected in congenital hypothyroidism. Choice C is incorrect as the thyroid gland should be producing normal levels of thyroxine shortly after birth, making this explanation unlikely in the context of congenital hypothyroidism.
3. A 5-year-old child is admitted to the pediatric unit with fever and pain secondary to a sickle cell crisis. Which intervention should the nurse implement first?
- A. Obtain a culture of any sputum or wound drainage
- B. Initiate normal saline IV at 50 ml/hr
- C. Administer a loading dose of penicillin IM
- D. Administer the initial dose of folic acid PO
Correct answer: B
Rationale: In a child with a sickle cell crisis, the priority intervention is to initiate normal saline IV at 50 ml/hr to manage dehydration and help alleviate pain. This intervention helps improve hydration status and supports the circulation of sickled red blood cells, reducing the risk of vaso-occlusive episodes and associated pain. Obtaining a culture of any sputum or wound drainage (Choice A) may be necessary but is not the initial priority. Administering a loading dose of penicillin IM (Choice C) is important but not the first intervention. Administering the initial dose of folic acid PO (Choice D) is beneficial but does not address the immediate need for hydration in a sickle cell crisis.
4. A two-year-old child with heart failure (HF) is admitted for replacement of a graft for coarctation of the aorta. Prior to administering the next dose of digoxin (Lanoxin), the nurse obtains an apical heart rate of 128 bpm. What action should the nurse take?
- A. Determine the pulse deficit
- B. Administer the scheduled dose
- C. Calculate the safe dose range
- D. Review the serum digoxin level
Correct answer: B
Rationale: The correct action for the nurse to take is to administer the scheduled dose of digoxin. A heart rate of 128 bpm in a two-year-old child with heart failure falls within the safe range for digoxin administration. It indicates that the child's heart rate is not excessively low, which could be a concern for administering digoxin. Therefore, proceeding with the scheduled dose is appropriate in this scenario. Determining the pulse deficit (Choice A) is not necessary in this situation as the heart rate is already obtained. Calculating the safe dose range (Choice C) is not required as the heart rate is within the safe range. Reviewing the serum digoxin level (Choice D) is not needed at this point since the heart rate indicates that administering the next dose is appropriate.
5. The healthcare provider is preparing to administer methylergonovine maleate (Methergine) to a postpartum client. Based on what assessment finding should the healthcare provider withhold the drug?
- A. Respiratory rate of 22 breaths/min
- B. A large amount of lochia rubra
- C. Blood pressure 149/90
- D. Positive Homan’s sign
Correct answer: C
Rationale: A blood pressure of 149/90 is an indication to withhold Methergine due to its potential to further increase blood pressure. Methergine is a medication that can cause vasoconstriction, leading to elevated blood pressure. In this case, administering Methergine could exacerbate the elevated blood pressure, posing a risk to the patient. Therefore, it is crucial to withhold the medication in the presence of hypertension to prevent adverse effects. The other options are not directly related to the administration of Methergine. A respiratory rate of 22 breaths/min is within the normal range. A large amount of lochia rubra may indicate normal postpartum bleeding. A positive Homan’s sign is associated with deep vein thrombosis, which is not a contraindication for administering Methergine.
