Decreased amounts of sleep, hyperactive Moro reflex, and difficulty feeding

Answer and Explanation

The Correct Answer is D

Choice A rationale
Hypothermia, decreased muscle tone, and a weak sucking reflex are not typically exhibited by newborns whose mothers are substance abusers. These symptoms could be indicative of other medical conditions.
Choice B rationale
Excessive sleep, a weak cry, and a diminished grasp reflex are not the most common behaviors exhibited by newborns of substance-abusing mothers.
Choice C rationale
Circumoral cyanosis, a hyperactive Babinski reflex, and constipation are not typically seen in newborns of substance-abusing mothers. These symptoms could be indicative of other medical conditions.
Choice D rationale
Newborns of substance-abusing mothers often exhibit decreased amounts of sleep, a hyperactive Moro reflex, and difficulty feeding. These symptoms are related to withdrawal from the substances the mother was using during pregnancy.

Correct Answer is C

Explanation

Choice A rationale
Hypothermia is not a typical response to phototherapy in an isolette. The heat from the phototherapy lights would typically prevent hypothermia.
Choice B rationale
Bradycardia, or a slow heart rate, is not a typical response to phototherapy in an isolette. If bradycardia occurs, it could be a sign of a serious condition that needs immediate medical attention.
Choice C rationale
Dehydration is a possible response to phototherapy in an isolette. The lights used in phototherapy can cause an infant to lose more water through their skin, leading to dehydration.
Choice D rationale
Decreased muscle tone is not a typical response to phototherapy in an isolette. If decreased muscle tone is observed, it could be a sign of a serious condition that needs immediate medical attention.

A. Negative pregnancy test B. Prothrombin time of 40 seconds C. Hemoglobin level of 10.1 g/dl D. Serum cholesterol of 140 mg/dl

Correct Answer is B

Explanation

Choice A rationale
A negative pregnancy test is not the priority in this case. While it’s important to rule out pregnancy as a cause of abnormal uterine bleeding (AUB), it’s not the most critical finding.

Choice B rationale
A prothrombin time of 40 seconds is significantly prolonged, indicating a potential coagulation disorder. This could explain the abnormal uterine bleeding and should be prioritized due to the risk of significant blood loss.
Choice C rationale
A hemoglobin level of 10.1 g/dl is slightly low but within acceptable limits for many individuals. While it could indicate some degree of anemia possibly due to chronic blood loss, it’s not as immediately concerning as a coagulation disorder.
Choice D rationale
A serum cholesterol level of 140 mg/dl is within the normal range and is not directly related to AUB1.
