1. What type of cells create exocrine secretions?

• A. alpha cells
• B. beta cells
• C. acinar cells
• D. plasma cells

Correct answer: C

Rationale: Acinar cells are responsible for creating exocrine secretions, such as enzymes and digestive juices. Alpha cells are found in the pancreas and are responsible for producing glucagon, beta cells produce insulin, and plasma cells are a type of white blood cell involved in immune responses. Therefore, the correct answer is acinar cells, as they specifically produce exocrine secretions.

2. What are the side effects of first-generation over-the-counter (OTC) antihistamines like diphenhydramine (Benadryl) and hydroxyzine (Atarax) in infants and children?

• A. Reye's syndrome.
• B. cholinergic effects.
• C. paradoxical CNS stimulation.
• D. nausea and diarrhea.

Correct answer: C

Rationale: The correct answer is paradoxical CNS stimulation. First-generation OTC antihistamines, such as diphenhydramine and hydroxyzine, can lead to paradoxical CNS stimulation in infants and children. This phenomenon is characterized by symptoms like excitement, euphoria, restlessness, and confusion, rather than the expected sedative effect. Due to this unexpected response, these antihistamines are used less frequently in pediatric populations. Reye's syndrome is a rare systemic response to a virus and is not a side effect of antihistamines. First-generation OTC antihistamines do not typically exhibit cholinergic effects. Nausea and diarrhea are uncommon side effects of these antihistamines and are less commonly observed than paradoxical CNS stimulation.

3. In conducting a community health fair for a group of middle-aged citizens, which statement should the nurse emphasize in reducing the risk of coronary heart disease?

• A. Participate in at least 30 minutes of moderate physical activity 3 to 5 days per week.
• B. Engage in an aerobic exercise class every day.
• C. Limit your alcohol intake to a moderate level.
• D. The best way to lose weight is to follow a balanced diet.

Correct answer: B

Rationale: Engaging in an aerobic exercise class every day is crucial in reducing the risk of coronary heart disease. Aerobic exercises help keep the heart in shape, lower blood pressure, and improve cholesterol levels. It is recommended to participate in at least 150 minutes of moderate-intensity aerobic exercise per week, which can be achieved by engaging in aerobic exercise daily. Choice A has been corrected to emphasize the frequency required to significantly reduce the risk of coronary heart disease. Choice C has been modified to suggest moderation in alcohol intake, as excessive alcohol consumption is harmful. Choice D is also incorrect as a balanced diet, not specifically high-protein, high-fat, is recommended to reduce the risk of coronary heart disease and maintain a healthy weight.

4. A nurse is instructing a patient about the warning signs of Digitalis side effects. Which of the following side effects should the nurse tell the patient are sometimes associated with excessive levels of Digitalis?

• A. Seizures
• B. Muscle weakness
• C. Depression
• D. Anxiety

Correct answer: B

Rationale: The correct answer is 'Muscle weakness.' Palpitations and muscle weakness are commonly associated with excessive levels of Digitalis. Seizures, depression, and anxiety are not typically linked to Digitalis toxicity. Seizures could be more related to other medications or conditions, while depression and anxiety are not commonly reported side effects of Digitalis.

5. Which of the following blood pressure parameters indicates PIH? Elevation over a baseline of:

• A. 30 mmHg systolic and/or 15 mmHg diastolic.
• B. 40 mmHg systolic and/or 20 mmHg diastolic.
• C. 10 mmHg systolic and/or 5 mmHg diastolic.
• D. 20 mmHg systolic and/or 20 mmHg diastolic.

Correct answer: A

Rationale: The correct answer is A: 30 mmHg systolic and/or 15 mmHg diastolic. These parameters indicate mild PIH (pregnancy-induced hypertension). Mild preeclampsia is characterized by an increase in systolic blood pressure greater than 30 mmHg or an increase in diastolic blood pressure greater than 15 mmHg, observed on two readings taken 6 hours apart (or reaching 140/90). Choice B (40 mmHg systolic and/or 20 mmHg diastolic) represents a more significant elevation and would indicate a more severe condition than mild PIH. Choices C (10 mmHg systolic and/or 5 mmHg diastolic) and D (20 mmHg systolic and/or 20 mmHg diastolic) do not meet the criteria for indicating PIH as they are below the accepted parameters for mild PIH.
