Adult Health Nursing Test Bank

Correct Answer: A

Rationale: The correct answer is A because zero absenteeism and tardiness of pupils indicate that the school nursing programs are effectively promoting student health and well-being. This outcome shows that students are healthy, engaged, and present in school, which is a key goal of school nursing initiatives. Choice B is incorrect as teachers being observers does not directly measure the effectiveness of the nursing programs. Choice C is incorrect as limited information hinders the success and impact of school health initiatives. Choice D is incorrect as constant visits and phone calls from parents may not necessarily reflect the success of the nursing programs.

Correct Answer: B

Rationale: The correct answer is B: Acute myocardial infarction (MI) is the most common cause of cardiogenic shock. During an MI, there is significant damage to the heart muscle, leading to a decrease in cardiac output and subsequent shock. This results in inadequate tissue perfusion and oxygen delivery. Choices A, C, and D are incorrect because decreased hemoglobin level (A) may lead to anemia but is not the most common cause of cardiogenic shock. Hypotension (C) is a symptom of shock, not the cause. Coronary artery disease (D) is a risk factor for MI but not the direct cause of cardiogenic shock.

Correct Answer: A

Rationale: The correct answer is A: Loss of self-tolerance. This is because autoimmune diseases result from a breakdown in the immune system's ability to distinguish between self and non-self antigens, leading to the production of antibodies against self-antigens. When self-tolerance is lost, immune cells mistakenly target the body's own tissues, causing tissue damage and inflammation. Choice B (Failure of innate immunity) is incorrect because autoimmune diseases are primarily driven by adaptive immunity rather than innate immunity. Choice C (Defective T cell activation) is incorrect as T cells play a critical role in the immune response to self-antigens in autoimmune diseases. Choice D (Impaired phagocytosis) is incorrect as phagocytosis is a mechanism primarily involved in the removal of pathogens, not in the development of autoimmune diseases.

Correct Answer: B

Rationale: The correct answer is B: Threatened abortion. Vaginal spotting and abdominal cramps are common symptoms of a threatened abortion, which occurs when there is a risk of miscarriage but the pregnancy remains viable. This diagnosis is likely after a vaginal examination to assess the cervix and presence of fetal heartbeat. A: Eclampsia is characterized by seizures in pregnancy due to high blood pressure, not typically presenting with vaginal spotting and cramps. C: Placenta previa involves the placenta covering the cervix, leading to painless vaginal bleeding, not associated with cramps. D: Abruptio placenta is premature separation of the placenta from the uterus, manifesting as painful bleeding, not typically with vaginal spotting and cramps.

Correct Answer: C

Rationale: The correct answer is C: Anaphylaxis. Anaphylaxis is the MOST severe form of an allergic reaction, including latex allergy. It is a systemic, potentially life-threatening reaction that can involve multiple organ systems. Symptoms can include difficulty breathing, swelling of the throat, a rapid drop in blood pressure, and cardiovascular collapse. Pruritus, erythema, and swelling (choice A) are common symptoms of allergic reactions but not specific to anaphylaxis. Asthma (choice B) can be a manifestation of latex allergy but is not the most severe form. Blisters and other skin lesions (choice D) are not typical of anaphylaxis but can occur in some cases of contact dermatitis from latex exposure.
