1. A client with end-stage cancer receiving Morphine has been prescribed Methylnaltrexone. The client's daughter asks about the purpose of Methylnaltrexone. Which response should the nurse provide?
- A. The medication will increase your mother's respirations.
- B. The medication will prevent dependence on the Morphine.
- C. The medication will relieve your mother's constipation.
- D. The medication works with the Morphine to increase pain relief.
Correct answer: C
Rationale: Methylnaltrexone is an opioid antagonist used to treat severe constipation unresponsive to laxatives in opioid-dependent clients. It functions by blocking the mu opioid receptors in the gastrointestinal tract, helping alleviate constipation associated with opioid use. Choices A, B, and D are incorrect. Methylnaltrexone does not increase respirations, prevent dependence on Morphine, or work with Morphine to increase pain relief; its primary purpose is to relieve opioid-induced constipation.
2. A healthcare professional is educating clients in an outpatient facility about the use of Insulin to treat type 1 Diabetes Mellitus. For which of the following types of insulin should the professional inform the clients to expect a peak effect 1 to 5 hr after administration?
- A. Insulin glargine
- B. NPH insulin
- C. Regular insulin
- D. Insulin lispro
Correct answer: C
Rationale: Regular insulin typically exhibits a peak effect approximately 1 to 5 hours after administration. It is important for clients to be aware of this timing to ensure optimal management of their blood glucose levels. Insulin glargine, NPH insulin, and Insulin lispro have different onset and peak times compared to Regular insulin. Insulin glargine has a slow, steady release with no pronounced peak, NPH insulin peaks around 4 to 12 hours after administration, and Insulin lispro has a rapid onset and a peak effect around 0.5 to 2.5 hours after administration. Therefore, Regular insulin is the correct choice for a peak effect within the specified time frame.
3. A healthcare provider in an emergency unit is reviewing the medical record of a client who is being evaluated for angle-closure glaucoma. Which of the following findings are indicative of this condition?
- A. Insidious onset of painless loss of vision
- B. Gradual reduction in peripheral vision
- C. Severe pain around the eyes
- D. Intraocular pressure of 12mm Hg
Correct answer: C
Rationale: Severe pain around the eyes that radiates over the face is a characteristic symptom of acute angle-closure glaucoma. This intense pain is typically accompanied by other symptoms such as blurred vision, halos around lights, redness in the eye, and sometimes nausea and vomiting. The acute rise in intraocular pressure leads to these symptoms, indicating a medical emergency that requires immediate attention to prevent vision loss. Choices A, B, and D are incorrect. Insidious onset of painless loss of vision is more suggestive of conditions like age-related macular degeneration or diabetic retinopathy. Gradual reduction in peripheral vision is commonly seen in conditions like open-angle glaucoma. An intraocular pressure of 12mm Hg is within the normal range and not indicative of the acute rise seen in angle-closure glaucoma.
4. A client has a new prescription for Ranitidine. Which of the following instructions should the nurse include?
- A. Take the medication with an antacid.
- B. Avoid drinking coffee while taking this medication.
- C. Take the medication at bedtime.
- D. Stop the medication if you develop a headache.
Correct answer: C
Rationale: The correct instruction for a client prescribed Ranitidine is to take the medication at bedtime. Ranitidine is best taken at night to reduce nighttime stomach acid production, providing optimal relief for conditions like gastroesophageal reflux disease (GERD) and ulcers.
5. Which of the following is not a side effect of the cholinoreceptor blocker (Atropine)?
- A. Increased pulse
- B. Diarrhea
- C. Constipation
- D. Mydriasis
Correct answer: B
Rationale: Atropine, an anticholinergic drug, commonly causes side effects like increased pulse, mydriasis (dilated pupils), and constipation due to its inhibitory effect on the parasympathetic nervous system. Diarrhea is not typically a side effect of Atropine, making it the correct answer.
