Outbreak of cases of typhoid fever occurs in the community. Nurse Keena should inform the residents that the transmission of the disease is through _______.

Correct Answer: C

Rationale: The correct answer is C: Food and water. Typhoid fever is primarily transmitted through contaminated food and water by the bacterium Salmonella typhi. The bacteria are shed in the feces of infected individuals and can contaminate water sources or food prepared with contaminated water. This transmission route aligns with the typical epidemiology of typhoid fever outbreaks. Now, let's discuss why the other choices are incorrect: A: A vector - Typhoid fever is not transmitted by a vector such as mosquitoes or ticks. B: Blood and body fluids - Typhoid fever is not typically spread through blood or body fluids but rather through ingestion of contaminated food or water. D: Air - Typhoid fever is not an airborne disease and is not transmitted through the air.

Correct Answer: B

Rationale: In this scenario, the pregnant woman is presenting with severe abdominal pain, passage of tissue, and cervical dilation with products of conception protruding through the cervical os at 12 weeks gestation. These are classic signs and symptoms of an incomplete abortion. Incomplete abortion occurs when not all of the products of conception are expelled from the uterus. It can present with vaginal bleeding, abdominal pain, cervical dilation, and passage of tissue. The management of incomplete abortion may involve expectant, medical, or surgical options depending on the clinical context and the patient's condition.

Correct Answer: C

Rationale: Rationale: - ARDS is characterized by severe hypoxemia and respiratory distress. - Tachypnea is a hallmark sign of ARDS due to the body's compensatory mechanism to increase oxygenation. - Hypoxemia refractory to supplemental oxygen signifies the inability to improve oxygen levels despite intervention. - Choices A, B, and D do not align with typical manifestations of ARDS, as they do not directly reflect severe hypoxemia or respiratory distress.

Correct Answer: D

Rationale: The correct answer is D: Professional Regulatory Board of Nursing. This board is specifically tasked with regulating the practice of the nursing profession, ensuring that nurses adhere to ethical and professional standards. The Department of Health (A) focuses on public health policies, not individual professional regulation. The Professional Regulation Commission (B) oversees various professions but does not specialize in nursing. The Civil Service Commission (C) deals with civil service matters, not professional nursing regulation. Therefore, the Professional Regulatory Board of Nursing is the most appropriate choice for regulating the nursing profession.

Correct Answer: B

Rationale: The correct answer is B: 20-Gauge. The smaller the gauge number, the larger the diameter of the catheter. Blood transfusions typically require a larger catheter size to prevent hemolysis and ensure proper flow. A 20-Gauge catheter is larger than 22-Gauge, 18-Gauge, and 12-Gauge, making it suitable for administering blood. 22-Gauge is too small and can cause hemolysis, 18-Gauge is smaller than the recommended size for blood transfusions, and 12-Gauge is too large and can cause damage to the vein.

Correct Answer: D

Rationale: The correct answer is D: Osteoporosis. Long-term use of inhaled corticosteroids can lead to decreased bone density and an increased risk of osteoporosis. Corticosteroids can interfere with calcium absorption and bone formation, resulting in bone weakening. Oral thrush (Choice A) is a common side effect of inhaled corticosteroids, but it is not associated with long-term use. Hypertension (Choice B) and hyperglycemia (Choice C) are more commonly seen with systemic corticosteroid use rather than inhaled corticosteroids.

Correct Answer: B

Rationale: The correct answer is B: Bright red and spurts with the heartbeat. This type of bleeding indicates arterial bleeding, which is oxygen-rich blood coming directly from the arteries. Arterial bleeding is bright red in color due to the high oxygen content and spurts with the heartbeat as it is under higher pressure. This rapid spurting is characteristic of arterial bleeding and requires immediate attention to control the bleeding source. Choices A, C, and D are incorrect because they describe characteristics of venous bleeding, not arterial bleeding. Venous bleeding is dark in color, flows slowly, and generally oozes as it is oxygen-depleted blood returning to the heart. Therefore, the correct answer is B based on the specific characteristics of arterial bleeding.

Correct Answer: D

Rationale: The correct answer is D because an ethical dilemma arises when there is a conflict between two or more ethical principles, leading to a difficult decision-making situation for Nurse Mauve. This involves weighing the benefits and consequences of each ethical principle to determine the best course of action. Choice A is incorrect as time pressure does not define an ethical dilemma. Choice B is incorrect because ethical dilemmas involve conflicting choices, not unclear ones. Choice C is incorrect as the conflict in an ethical dilemma is not necessarily with a superior but can be internal or with other stakeholders.

Correct Answer: A

Rationale: The correct answer is A: Central retinal artery occlusion. This condition presents with sudden-onset, painless vision loss, cherry-red spot at the macula due to lack of blood flow, and attenuated retinal vessels. The cherry-red spot is due to the transparency of the fovea when there is ischemia in the surrounding retina. Central retinal vein occlusion (B) presents with sudden vision loss accompanied by retinal hemorrhages and dilated tortuous veins. Retinal detachment (C) typically presents with sudden flashes, floaters, and a curtain-like visual field defect. Acute angle-closure glaucoma (D) presents with severe eye pain, blurred vision, halos around lights, and a fixed mid-dilated pupil.
