The patient asks Nurse Vera, when could you hear the fetal heart of my baby? Which of the following should be the BEST answer of Nurse Vera?

Correct Answer: C

Rationale: The correct answer is C: Fifth month. Nurse Vera should explain that the fetal heart can typically be heard using a Doppler ultrasound device around the fifth month of pregnancy. This is because the baby's heart is developed enough to produce audible sounds by this time. Choices A, B, and D are incorrect because in the ninth month, the baby is ready for delivery, in the third month the heart is still developing, and in the first month the heart is just beginning to form and is not yet audible.

Correct Answer: D

Rationale: The correct answer is D: Feeling of hopelessness. Adolescents who feel hopeless are at a higher risk of attempting suicide due to a lack of belief in positive outcomes. This feeling can lead to a sense of being trapped and unable to see a way out. Depressed mood (A) can contribute to suicide risk, but specifically feeling hopeless is a more direct predictor. Feeling of euphoria (B) and joyful mood (C) are actually less likely to be associated with suicide attempts, as they may temporarily mask underlying issues or provide a sense of distraction. Hopelessness is a key psychological factor that can lead to suicidal thoughts and behaviors in adolescents.

Correct Answer: C

Rationale: The correct answer is C: Cells die. In Alzheimer's disease, there is a progressive degeneration of brain cells, leading to cell death. This results in a loss of important brain functions such as memory, cognition, and eventually, bodily functions. The atrophy of the brain stem (choice A) is not a characteristic feature of Alzheimer's. Fluid buildup (choice B) is not a primary mechanism of the disease. Tissue swelling (choice D) is not typically associated with the progression of Alzheimer's; rather, there is a gradual loss of brain tissue due to cell death.

Correct Answer: B

Rationale: The correct answer is B: Equity in services. Collaboration and teamwork in public health are crucial to ensure equal access to services for all populations, regardless of their background or socioeconomic status. By working together, public health professionals can identify disparities and implement strategies to address them, ultimately leading to improved equity in healthcare services. A: Staff performance - While collaboration and teamwork can positively impact staff performance, the primary focus in public health is on achieving equity in services for all individuals. C: Proper use of resources - Collaboration can help optimize resource allocation, but the main goal in public health is to ensure equitable access to services. D: Quality healthcare - While collaboration can enhance the quality of healthcare, the primary emphasis in public health is on promoting equity in services to address health disparities.

Correct Answer: D

Rationale: The correct answer is D because a journal article about a study using large, previously unpublished databases is a primary source as it presents original research findings firsthand. It contributes new knowledge to the field. A textbook (A) compiles existing information, not original research. A doctoral dissertation (B) critiques research but is not a primary source. A published commentary (C) interprets others' findings, making it a secondary source.

Correct Answer: B

Rationale: The correct answer is B because the death of a spouse, child, or death by suicide are all significant losses that can lead to complicated grief due to the intensity of emotions and the disruption of daily life. These experiences can result in prolonged and severe grieving processes that may require professional intervention. Explanation for other choices: A: Childbirth, marriage, and divorce are not typically considered risk factors for complicated grief as they are more commonly associated with expected life events that may involve grief but not necessarily lead to complicated grief. C: Inadequate perception of the grieving process may contribute to difficulties in coping with grief but is not a direct risk factor for complicated grief. D: While inadequate support can impact the grieving process, and old age may present unique challenges, they are not specific risk factors for complicated grief compared to the profound loss experienced in choice B.

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: C

Rationale: The correct answer is C, to have a limited intake of sodium. Lithium can lead to increased sodium levels in the body, potentially causing toxicity. By limiting sodium intake, the patient can maintain a balance and prevent adverse effects. Choice A is incorrect as tyramine content is not directly related to lithium intake. Choice B is incorrect as fluid intake does not have a significant impact on lithium levels. Choice D is incorrect because an adequate intake of sodium can lead to worsening lithium toxicity.

Correct Answer: B

Rationale: Step 1: Furosemide is a loop diuretic that works in the ascending loop of Henle to inhibit sodium and chloride reabsorption. Step 2: Inhibition of sodium reabsorption leads to increased water and electrolyte excretion, including potassium. Step 3: Increased potassium excretion can lead to hypokalemia, which is a common side effect of loop diuretics like furosemide. Step 4: Hypokalemia can be dangerous, especially in patients with congestive heart failure, as it can worsen cardiac function and lead to arrhythmias. Step 5: Therefore, patients with a history of congestive heart failure prescribed furosemide are at risk for developing hypokalemia due to increased potassium excretion.
