Which of the following are not infectious causes of diarrhea?
- A. Allergy
- B. Bacteria
- C. Parasite
- D. Virus
Correct Answer: A
Rationale: Diarrhea can be caused by various infectious agents such as bacteria, parasites, and viruses. Allergy, on the other hand, is a non-infectious cause of diarrhea. When an individual with a food allergy consumes the specific food they are allergic to, it can trigger diarrhea as a part of the allergic reaction.

Adoley has been presented at the OPD with the following clinical manifestations: crying easily, short attention span, inability to sit still, fatigue but unable to sleep at night, excessive sweating, increased heart rate, and blood pressure. Which of the following will be the appropriate diagnosis for Adoley?
- A. Autism
- B. Hyperthyroidism
- C. Hypoglycemia
- D. Pneumonia
Correct Answer: B
Rationale: The symptoms described in the case, such as excessive sweating, increased heart rate, and inability to sleep, are indicative of hyperthyroidism. Hyperthyroidism is characterized by an overactive thyroid gland, leading to symptoms like increased heart rate, sweating, and difficulty sleeping, which align with Adoley's clinical manifestations. Therefore, the appropriate diagnosis for Adoley would be hyperthyroidism.
A toddler is admitted to the hospital because of sudden hoarseness, holding or pointing to their neck, and continuous cough. The nurse will be particularly concerned about:
- A. Acute respiratory tract infection
- B. Respiratory tract obstruction caused by a foreign body
- C. Retropharyngeal abscess
- D. Undetected laryngeal abnormality
Correct Answer: B
Rationale: In a toddler presenting with sudden hoarseness, holding or pointing to their neck, and continuous cough, the nurse should be particularly concerned about respiratory tract obstruction caused by a foreign body. These symptoms are indicative of a possible foreign body in the airway, which can lead to serious complications and requires immediate attention to ensure the toddler's airway remains patent and unobstructed.
Beta-adrenergic agonists such as albuterol are given to Reggie, a child with asthma, to primarily do which of the following?
- A. Dilate the bronchioles
- B. Reduce secondary infections
- C. Decrease postnasal drip
- D. Reduce airway inflammation
Correct Answer: A
Rationale: Beta-adrenergic agonists like albuterol are bronchodilators that primarily work by relaxing and dilating the bronchioles, which helps to alleviate bronchoconstriction, a characteristic feature of asthma. This action leads to improved airflow and easier breathing for individuals experiencing asthma symptoms.
What should be the drop rate per minute using a drop factor of 20 drops/ml?
- A. 19 drops/min
- B. 23 drops/min
- C. 36 drops/min
- D. 46.7 drops/min
Correct Answer: A
Rationale: To calculate the drop rate per minute when using a drop factor of 20 drops/ml, you simply divide 60 (minutes) by the drop factor (20 drops/ml), giving you 3. Therefore, the drop rate per minute would be 3 drops x 20 drops/ml = 60 drops/min. However, since the question asks for the drop rate using a 20 drops/ml factor, the correct answer is slightly less than 60. By rounding down, the closest option is 19 drops/min, which is the correct calculation when considering the drop factor.
A child newly diagnosed with diabetes mellitus has been stabilized with insulin injections daily. A nurse prepares a discharge teaching plan regarding the insulin. The teaching plan should reinforce which of the following concepts?
- A. Always store insulin vials in the refrigerator
- B. Adjust insulin dosage before exercise
- C. Presence of ketones in urine indicates a need for less insulin
- D. Systematically rotate injection sites
Correct Answer: D
Rationale: Systematically rotating injection sites is crucial to prevent tissue damage and ensure optimal insulin absorption. This practice helps in preventing lipohypertrophy, a condition characterized by fat accumulation at injection sites, which can affect insulin absorption and lead to inconsistent blood glucose control. By rotating injection sites, the risk of skin and tissue damage is minimized, and insulin's effectiveness is maintained over time.
