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.

Correct Answer: B

Rationale: The primary reason for encouraging the laboring client to void regularly is to prevent an over-distended bladder, which could impede the descent of the fetus, prolong labor, and be at risk for trauma during delivery. Choice A is incorrect because the difficulty in emptying the bladder during delivery is not the main reason for this nursing intervention. Choice C is incorrect as it pertains to obtaining urine specimens for glucose and protein, not the primary reason for encouraging voiding. Choice D is incorrect because although frequent voiding can indeed minimize the need for catheterization, the primary reason is to prevent an over-distended bladder and potential complications.

Correct Answer: B

Rationale: Smoking during pregnancy is associated with intrauterine growth restriction, leading to lower birth weights. This occurs due to the harmful effects of smoking on fetal development, which can result in reduced nutrient and oxygen supply to the fetus, impacting its overall growth and leading to lower birth weights. Choices A, C, and D are incorrect as smoking during pregnancy primarily affects fetal growth and development, leading to lower birth weights rather than lower Apgar scores, respiratory distress, or a higher rate of congenital anomalies.

Correct Answer: C

Rationale: An abnormal oral glucose tolerance test result is indicative of gestational diabetes. This test is crucial in diagnosing gestational diabetes as it evaluates how well the body processes glucose after a sugary drink. Reporting abnormal results promptly allows for timely intervention and management to ensure the well-being of both the mother and the baby. The other options are not the primary tests used to diagnose gestational diabetes. Hemoglobin A1C is not recommended for diagnosing gestational diabetes as it reflects long-term glucose control. Postprandial blood glucose and fasting blood glucose tests are not as sensitive as the oral glucose tolerance test for diagnosing gestational diabetes.

Correct Answer: C

Rationale: A decrease in respiratory rate from 24 to 16 indicates that magnesium sulfate is effectively reducing central nervous system irritability, a desired therapeutic effect. This decrease in respiratory rate signifies that the drug has reached a therapeutic level to control symptoms of severe pregnancy-induced hypertension. Choices A, B, and D are incorrect because 4+ reflexes, urinary output, and body temperature are not direct indicators of achieving a therapeutic level of magnesium sulfate for controlling PIH symptoms.
