Correct Answer: D

Rationale: Rationale for Correct Answer (
D): Checking with the pharmacy for availability of liquid forms of medications is the best action because it reduces the risk of clogging the nasogastric tube. Liquid medications are less likely to cause blockages compared to nonliquid medications. Additionally, liquid forms are easier to administer through the tube. By using liquid medications, the nurse can ensure that the medications flow smoothly through the tube without causing any obstructions.

Summary of Incorrect

Choices:
A: Instilling nonliquid medications without diluting can increase the risk of tube clogging.
B: Irrigating the tube with water after all medications are given may not prevent clogging effectively and could introduce unnecessary moisture into the tube.
C: Mixing all medications together can lead to potential drug interactions and may not address the issue of tube clogging effectively.

Correct Answer: C

Rationale: The correct answer is C: Normal deep tendon reflexes. This indicates a therapeutic level of magnesium sulfate as it shows that the medication is effectively preventing hyperreflexia, a common sign of magnesium toxicity. Drowsiness (choice
A) can indicate toxicity. Urinary output of 20 mL/hour (choice
B) is not specific to magnesium sulfate levels. Respiratory rate of 10 to 12 breaths per minute (choice
D) is indicative of respiratory depression, a sign of magnesium toxicity. Thus, choice C is the best assessment to indicate a therapeutic level of medication in a patient with preeclampsia taking magnesium sulfate.

Correct Answer: A

Rationale: The correct answer is A: Gay, bisexual, and other men who have sex with men. This group currently has the highest risk of contracting HIV due to various factors such as higher prevalence within this population, risky sexual behaviors, and limited access to healthcare services. Men who have sex with men have been disproportionately affected by HIV/AIDS since the beginning of the epidemic. Recreational drug users and blood transfusion recipients have lower overall risk compared to men who have sex with men. Health care providers, although at risk of occupational exposure, have lower risk compared to the other groups mentioned.

Correct Answer: C

Rationale: The correct answer is C because it includes fiber-rich whole wheat bread, grapes, and walnuts which promote healthy bowel elimination. Whole wheat bread and fruits provide dietary fiber that aids in digestion and prevents constipation. Walnuts are high in omega-3 fatty acids which can also help with bowel regularity.

Option A (Broccoli and cheese soup with potato bread) lacks fiber and may cause constipation due to the low fiber content. Option B (Turkey and mashed potatoes with brown gravy) may be low in fiber and high in fat, which can slow down digestion. Option D (Dinner salad topped with hard-boiled eggs, cheese, and fat-free dressing) is a healthier choice but may lack sufficient fiber for promoting healthy bowel elimination compared to option C.

Correct Answer: A

Rationale: The correct answer is A. Postoperative day 6 following tympanoplasty and mastoidectomy is still within the early phase of recovery, where occasional sharp, shooting pains in the affected ear can be expected due to the healing process. Here's a step-by-step rationale:
1. Timing: It is only day 6 post-surgery, so it is normal to experience some pain as part of the healing process.
2. Nature of pain: Sharp, shooting pains are common post-surgery due to tissue healing and nerve regeneration.
3. Lack of other symptoms: The patient did not report any other concerning symptoms like fever or discharge, which would be more indicative of an infection.
4. Unlikely complications: Spontaneous rupture of the tympanic membrane or unsuccessful surgery would typically present with more severe and consistent symptoms.

Summary:
- B: Unlikely as there are no other signs of infection.
- C: Unlikely as the pain is described as occasional and sharp.
- D:
