A nurse is assessing a client who has a new diagnosis of anorexia nervosa. Which of the following findings should the nurse expect?
Bradycardia
Hyperactive bowel sounds
Dental erosion
Hypertension.
The Correct Answer is A
Choice A rationale: Bradycardia
Bradycardia, or an abnormally slow heart rate, is a common cardiovascular manifestation in individuals with anorexia nervosa. It is often a result of the body’s adaptive response to conserve energy due to severe malnutrition and reduced caloric intake. This is because the body is trying to conserve as much energy as possible, and one way it does this is by slowing down the heart rate. This can be dangerous, however, as it can lead to fainting, heart failure, or even death if not properly managed.
Choice B rationale: Hyperactive bowel sounds
Hyperactive bowel sounds are not typically associated with anorexia nervosa. Instead, individuals with this disorder often experience constipation and other gastrointestinal issues due to inadequate food intake. The lack of food intake can slow down the digestive process, leading to these symptoms.
Choice C rationale: Dental erosion
Dental erosion can be a consequence of anorexia nervosa, but it is more commonly associated with bulimia nervosa due to the frequent vomiting that characterizes this disorder. The stomach acid that comes into contact with the teeth during vomiting can cause the enamel to erode. However, it’s important to note that not all individuals with anorexia nervosa will experience this symptom.
Choice D rationale: Hypertension
Hypertension, or high blood pressure, is not typically associated with anorexia nervosa. In fact, low blood pressure (hypotension) is more common due to the decreased volume of blood in the body from insufficient nutrition.
Hypertension is more commonly associated with conditions such as obesity and metabolic syndrome.

Correct Answer is C
Explanation
Rationale:
Choice A is incorrect. Alprazolam does not have any known dietary interactions with aged cheeses. This information is specific to monoamine oxidase inhibitors (MAOIs), not benzodiazepines like alprazolam.
Choice B is incorrect. While some benzodiazepines can have side effects like drowsiness or dizziness that might indirectly affect blood pressure, alprazolam itself is not known to directly cause an increase in blood pressure.
Choice D is incorrect. Doubling the next dose of medication if a dose is missed is dangerous and can lead to overdose and increased risk of serious side effects. The client should be instructed to contact their doctor if they miss a dose.
Choice C is correct. Alprazolam is a pregnancy category D medication, meaning it has positive evidence of fetal risk. Studies have shown an increased risk of birth defects, including cleft lip and palate, in babies exposed to alprazolam during pregnancy. Therefore, it is crucial for women of childbearing age to use a reliable form of contraception while taking alprazolam to prevent unintended pregnancy and potential harm to the fetus.
Additional teaching points for the nurse:
The nurse should inform the client about the specific risks associated with alprazolam during pregnancy and the importance of discussing alternative treatment options if pregnancy is desired.
The nurse should emphasize the importance of using a reliable form of contraception that is effective both during and after treatment with alprazolam, as the medication can remain in the system for some time after the last dose.
The nurse should provide the client with resources on contraception and reproductive health, and encourage her to talk to her doctor about any s or concerns she may have.
Correct Answer is ["2"]
Explanation
The nurse should administer 2 tablets per dose.
Rationale:
Step 1: Determine the desired dose of diphenhydramine. The desired dose is 50 mg.
Step 2: Determine the available tablet strength. The available tablet strength is 25 mg.
Step 3: Divide the desired dose by the tablet strength to determine the number of tablets needed. 50 mg / 25 mg/tablet = 2 tablets
Therefore, the nurse should administer 2 tablets of diphenhydramine 25 mg per dose to achieve the desired dose of 50 mg.
