A nurse is assessing a client who is experiencing acute amphetamine toxicity. Which of the following findings should the nurse expect?
Tachycardia
Headache
Increased appetite
Pupil constriction
The Correct Answer is A
A. Tachycardia: Amphetamines are central nervous system stimulants that increase sympathetic nervous system activity. Tachycardia is a common manifestation of acute toxicity, along with hypertension, hyperthermia, and agitation. Monitoring cardiovascular status is essential to prevent complications.
B. Headache: While headaches can occur with amphetamine use, they are not a primary or consistent finding in acute toxicity. More prominent signs are cardiovascular and neurological stimulation rather than mild symptoms like headache.
C. Increased appetite: Amphetamines typically suppress appetite rather than increase it. Clients experiencing acute toxicity are more likely to have decreased hunger due to stimulant effects on the hypothalamus.
D. Pupil constriction: Amphetamines usually cause mydriasis (pupil dilation) due to sympathetic stimulation. Pupil constriction is more characteristic of opioid toxicity rather than amphetamine toxicity.

Correct Answer is D
Explanation
A. Administer methylphenidate daily: Stimulant medications like methylphenidate are not appropriate for anorexia nervosa treatment, as they can suppress appetite and worsen weight loss. They are contraindicated in clients with this disorder.
B. Weigh the client twice a week: Weighing twice a week is insufficient for clients with anorexia nervosa. Daily, same-time, same-clothing weights are recommended to monitor progress and detect potential medical complications associated with malnutrition.
C. Focus conversations around food at mealtimes: Focusing on food can increase anxiety and reinforce preoccupations with eating. Instead, conversations should be neutral or supportive, promoting a calm and therapeutic mealtime environment.
D. Inform the client of the specific duration of meals: Setting clear expectations for meal duration helps reduce anxiety, provides structure, and supports adherence to nutritional rehabilitation. It is an effective intervention in the care plan for clients with anorexia nervosa.
Correct Answer is A
Explanation
A. Assess for bladder distention: A full bladder can prevent the uterus from contracting effectively, leading to a boggy fundus and increased risk of postpartum hemorrhage. Assessing and addressing bladder distention is the priority because it directly impacts uterine tone and hemorrhage prevention.
B. Apply supplemental oxygen via nonrebreather mask: Oxygen may be necessary if the client shows signs of hypoxia or shock, but it does not address the primary cause of a boggy uterus. The priority is to correct the underlying issue affecting uterine contraction.
C. Administer intramuscular methylergonovine: Methylergonovine is used to promote uterine contraction, but pharmacologic intervention should follow initial assessment to identify reversible causes such as bladder distention. Administering medication without assessment could overlook a correctable mechanical issue.
D. Analyze coagulation studies: Coagulation studies are important if bleeding persists or coagulopathy is suspected, but they are not the immediate priority in a client with a boggy fundus shortly after birth. Immediate interventions to promote uterine contraction take precedence.
