Adult Health Nursing Answer Key

Correct Answer: D

Rationale: Informed consent is a critical ethical requirement in research involving human participants. In this study scenario, it is crucial that both the participants and their parents provide consent. The involvement of the parents is important, especially when the participants are minors or vulnerable individuals who may not fully understand the study's implications or risks. By obtaining consent from both the participants and their parents, researchers can ensure that everyone involved is aware of what participation in the study entails, including any potential risks or benefits. This approach upholds the principles of autonomy, respect for individuals, and ethical research conduct.

Correct Answer: D

Rationale: The most likely cause of the sudden onset of severe abdominal pain and dark red vaginal bleeding with a tender, firm uterus at 28 weeks gestation is abruptio placentae. Abruptio placentae, also known as placental abruption, is the premature separation of the placenta from the uterine wall before delivery. This condition can be life-threatening to both the mother and the fetus, as it can lead to severe bleeding and compromise the oxygen and nutrients supply to the fetus. The presentation typically includes severe abdominal pain, dark red or maroon vaginal bleeding, uterine tenderness, and a firm uterus due to the blood accumulation behind the placenta. Prompt recognition and intervention are crucial to prevent adverse maternal and fetal outcomes.

Correct Answer: B

Rationale: The nurse's best approach to address the patient's fear of needles before a blood draw is to provide the patient with information about relaxation techniques and distraction methods (Option B). Dismissing the patient's fear (Option A), ignoring the fear and proceeding quickly (Option C), or telling the patient that the fear is irrational and unfounded (Option D) would not be helpful and could potentially escalate the patient's anxiety. Providing information on relaxation techniques such as deep breathing or visualization, as well as distraction methods like listening to music or engaging in conversation, can help the patient feel more comfortable and reduce their fear and anxiety during the blood draw procedure. It is important for the nurse to acknowledge and address the patient's concerns in a supportive and empathetic manner to build trust and ensure a successful blood draw experience.

Correct Answer: A

Rationale: The clinical presentation described is highly suggestive of acute angle-closure glaucoma. This condition typically presents with sudden-onset severe eye pain, headache, nausea, and vomiting. The red eye, steamy cornea (due to corneal edema), and mid-dilated, non-reactive pupil (from the unopposed force of the dilator muscle) are classic findings in acute angle-closure glaucoma. The increase in intraocular pressure compromises blood flow to the eye, leading to symptoms of blurred vision and possible visual loss. Immediate management usually involves lowering intraocular pressure with medications or surgical intervention to prevent vision loss. Central retinal artery occlusion, optic neuritis, and corneal ulcer typically present with different clinical features and are not consistent with the described presentation.

Correct Answer: B

Rationale: Convenience sampling involves selecting participants who are readily available or easy to access. In this scenario, choosing to interview nurses who happen to be in the conference room where the activity is scheduled falls under convenience sampling as they are easily accessible at that moment. While convenience sampling may be convenient, it may introduce bias and may not represent the entire population accurately.
