1. Non-pharmacological techniques can help lower blood pressure. Which of the following is not considered one of these types of techniques?

• A. Dietary changes
• B. Multivitamins
• C. Smoking cessation
• D. Limiting caffeine

Correct answer: B

Rationale: Multivitamins are not typically considered a non-pharmacological technique for lowering blood pressure. While dietary changes, smoking cessation, and limiting caffeine intake can positively impact blood pressure levels, multivitamins are generally not specifically recommended as a primary intervention for this purpose. Dietary changes can include reducing salt intake and increasing potassium-rich foods, which are known to help manage blood pressure. Smoking cessation is crucial due to the negative impact of smoking on blood pressure and overall cardiovascular health. Limiting caffeine intake is advised as excessive caffeine consumption can lead to a temporary increase in blood pressure. Therefore, focusing on lifestyle modifications like healthy eating, smoking cessation, and caffeine reduction is more effective in managing blood pressure than relying on multivitamins.

2. Which of the following is NOT an infectious cause of diarrheal diseases?

• A. Allergy
• B. Bacterial
• C. Parasitic
• D. Viral

Correct answer: A

Rationale: Allergy is the correct answer as it is a non-infectious cause of diarrheal diseases. While bacterial, parasitic, and viral infections can lead to diarrhea by affecting the gastrointestinal tract, allergies are immune system reactions triggered by specific substances and are not caused by infectious agents. Bacterial, parasitic, and viral infections are known to cause infectious diarrhea, making choices B, C, and D incorrect.

3. What action should you take if a newborn's heart rate is 50 beats/min?

• A. Begin chest compressions.
• B. Reassess in 30 seconds.
• C. Administer blow-by oxygen.
• D. Start positive-pressure ventilations.

Correct answer: D

Rationale: If a newborn's heart rate is below 60 beats per minute, the appropriate action is to start positive-pressure ventilations. Ventilations help deliver oxygen to the newborn's body and support respiratory function, which is critical in cases of bradycardia. Chest compressions are not recommended until the heart rate is below 60 despite adequate ventilation. Reassessment is essential but not the immediate action required in this scenario. Administering blow-by oxygen alone may not effectively address the underlying cause of bradycardia, making positive-pressure ventilations the priority intervention in this case.

4. What are the MOST important initial steps in assessing and managing a newborn?

• A. Drying and warming the infant, obtaining an APGAR score.
• B. Clearing the airway, keeping the infant warm.
• C. Suctioning the airway, obtaining a heart rate.
• D. Keeping the infant warm, counting respirations.

Correct answer: B

Rationale: The most crucial initial steps in assessing and managing a newborn involve clearing the airway to ensure proper breathing and keeping the infant warm to maintain body temperature. Airway clearance helps prevent respiratory distress, while warmth is essential to prevent hypothermia, a common issue in newborns. These steps are vital in the immediate care of a newborn to support their transition to extrauterine life and ensure their well-being. Choice A is incorrect because obtaining an APGAR score is important but not as critical as clearing the airway. Choice C is incorrect as suctioning the airway is not always necessary and obtaining a heart rate is secondary to ensuring a clear airway and warmth. Choice D is incorrect because counting respirations is not as immediate and crucial as clearing the airway.

5. Which of the following is NOT a function of hormones?

• A. Producing new offspring
• B. Promoting growth and beauty
• C. Maintaining body temperature
• D. Fighting infections

Correct answer: A

Rationale: Hormones play various roles in the body, such as promoting growth and beauty, maintaining body temperature, and fighting infections. However, producing new offspring is not a direct function of hormones. Reproduction is primarily regulated by other factors like the reproductive system. Choice B is incorrect because hormones can indeed influence growth but not specifically 'beauty.' Choice C is incorrect as hormones can help regulate body temperature indirectly. Choice D is incorrect as hormones like cytokines can be involved in the body's immune response to fight infections.
