The nurse is caring for a child with suspected diabetes insipidus. Which clinical manifestation would be observable?
Oliguria
Glycosuria
Nausea and vomiting
Polydipsia
The Correct Answer is D
Diabetes insipidus is a disorder of the posterior pituitary gland that causes a deficiency of antidiuretic hormone (ADH). This leads to excessive urination (polyuria) and excessive thirst (polydipsia) as the body tries to balance the fluid loss. These symptoms may be so severe that the child does little other than drink and urinate.
Choice A is wrong because oliguria means decreased urine production and is not associated with diabetes insipidus.
Choice B is wrong because glycosuria means glucose in the urine and is associated with diabetes mellitus, not diabetes insipidus.
Choice C is wrong because nausea and vomiting are associated with inappropriate ADH secretion (SIADH), which causes fluid retention and hyponatremia, not diabetes insipidus.

Correct Answer is C
Explanation
The patient is showing signs of magnesium toxicity, such as respiratory depression, hyporeflexia, and flushing.
Magnesium sulfate is a high-alert medication that can cause serious adverse effects if not monitored closely.
The nurse should stop the infusion immediately and notify the provider.
Choice A is wrong because calling for a stat magnesium sulfate level will not address the immediate problem of toxicity.
The nurse should act quickly to prevent further complications.
Choice B is wrong because administering oxygen will not reverse the effects of magnesium toxicity.
Oxygen may be helpful for respiratory distress, but it will not correct the underlying cause.
Choice D is wrong because hydralazine is an antihypertensive medication that lowers blood pressure.
The patient’s blood pressure is already within the normal range for a pregnant woman with preeclampsia (140-160/90-110 mm Hg).
Hydralazine may cause hypotension and fetal distress.
Correct Answer is B
Explanation
This is because a patent ductus arteriosus is a congenital heart defect that involves a defect in which the fetal shunt between the aorta and the pulmonary artery fails to close. This causes a continuous machinery-like murmur that can be heard on auscultation.
Choice A is wrong because pulmonary stenosis is a narrowing of the pulmonary valve or artery that obstructs blood flow to the lungs. It causes a systolic ejection murmur that is best heard at the upper left sternal border.
Choice C is wrong because the ventricular septal defect is a hole in the wall between the ventricles that allows blood to flow from the left to the right side of the heart. It causes a loud, harsh holosystolic murmur that is best heard at the left lower sternal border.
Choice D is wrong because coarctation of the aorta is a narrowing of the aorta that reduces blood flow to the lower body. It causes a systolic murmur that radiates to the back and weak or absent femoral pulses.
