A nurse is caring for a client who received two doses of albuterol via nebulizer. Which of the following findings should the nurse expect during an assessment?
Bradycardia
Wheezing
Tremors
Sleepiness
The Correct Answer is C
Rationale:
A. Bradycardia: Albuterol can cause an increase in heart rate (tachycardia) as a common side effect, not a decrease in heart rate, so bradycardia would not be expected.
B. Wheezing: Albuterol is used to relieve wheezing by causing bronchodilation, so continued wheezing after administration would suggest ineffective treatment rather than being an expected finding.
C. Tremors: Tremors are a common side effect of albuterol due to its stimulation of beta-2 receptors in the muscles. This is often seen after nebulizer treatments.
D. Sleepiness: Albuterol generally causes stimulation of the central nervous system, leading to restlessness or nervousness, not sleepiness.

Correct Answer is B
Explanation
Rationale:
A. A decrease in the amount of gastric acid production: Alosetron is not used to decrease gastric acid production. This effect is more associated with medications such as proton pump inhibitors or H2 blockers.
B. A decrease in the frequency of defecation: Alosetron is used to treat irritable bowel syndrome with diarrhea (IBS-D) by reducing bowel movement frequency and improving stool consistency.
C. An increase in gastric motility: Alosetron works by decreasing intestinal motility, which helps reduce diarrhea, not by increasing it.
D. An increase in the absorption of water into the intestine: Alosetron does not specifically increase water absorption into the intestine. Its primary effect is slowing intestinal transit to reduce diarrhea.
Correct Answer is B
Explanation
Rationale:
A. Diazepam is a benzodiazepine used for anxiety and sedation but is not effective for treating malignant hyperthermia.
B. Dantrolene is the specific antidote for malignant hyperthermia, and the nurse should expect to administer it to help reduce the severe muscle contractions and hypermetabolism associated with this condition.
C. Cyclobenzaprine is a muscle relaxant used for muscle spasms but is not indicated for malignant hyperthermia.
D. Metaxalone is also a muscle relaxant, but like cyclobenzaprine, it is not effective for managing malignant hyperthermia and would not be used in this situation.
