foundations of nursing test bank

Correct Answer: B

Rationale: The correct answer is B because it shows an understanding that being HIV-positive does not guarantee transmission to the baby. The statement acknowledges the possibility of the baby not being affected, which demonstrates awareness of the varying outcomes. Choice A is incorrect as it assumes abortion is the only option. Choice C is incorrect as it makes an extreme and inaccurate claim. Choice D is incorrect as pregnancy does not decrease the chance of developing AIDS.

Correct Answer: A

Rationale: The correct answer is A: Diabetes. Erectile dysfunction can be caused by organic factors, such as diabetes, which affects blood flow and nerve function. Diabetes can lead to damage of blood vessels and nerves, impacting the ability to achieve and maintain an erection. Testosterone deficiency (choice B) can also contribute to erectile dysfunction, but it is not an organic cause. Anxiety (choice C) and depression (choice D) are psychological factors that can lead to erectile dysfunction, not organic causes. Parkinsonism (choice E) can affect sexual function, but it is not a common organic cause of erectile dysfunction.

Correct Answer: C

Rationale: The correct answer is C: Identifying the offending agent, if possible. This is prioritized in contact dermatitis to prevent further exposure and recurrence. By identifying the specific irritant or allergen, the nurse can guide the patient in avoiding it, leading to effective management. Choices A, B, and D are incorrect because while promoting adequate perfusion, safe use of topical antihistamines, and teaching the use of an EpiPen may be relevant in certain situations, they do not directly address the root cause of contact dermatitis, which is exposure to the offending agent.

Correct Answer: B

Rationale: The correct answer is B because turning off the television is necessary for effective learning and communication between the nurse preceptor and student nurse. Watching TV can be distracting and disrespectful during the learning process. Choices A, C, and D are incorrect because chewing gum, speaking clearly and loudly, and using at least 14-point print are behaviors that do not hinder the learning process and can be acceptable in a professional setting.

Correct Answer: C

Rationale: The correct answer is C because the severity of an anaphylactic reaction can vary greatly from one episode to another in the same patient. Anaphylactic reactions are unpredictable and can be influenced by various factors such as the amount of allergen exposure, individual immune response, underlying health conditions, and concurrent medications. Therefore, it is not possible to reliably gauge the severity of a patient's anaphylactic reaction even if it has occurred repeatedly in the past. Choice A is incorrect because the onset of symptoms alone is not a reliable predictor of the severity of the reaction. Choice B is incorrect as well because there is no set formula to predict that the reaction will be one-third more severe than the patient's last reaction. Choice D is incorrect because stating that the reaction will generally be slightly less severe than the last reaction is also not accurate or supported by evidence.
