Nursing Elites

1. What should the nurse include in the insulin administration instruction for the parents of a child being discharged on insulin?

• A. Insert the needle and aspirate before injecting
• B. Inject insulin into the extremity to be exercised to improve absorption
• C. The muscles in the abdomen and thigh are the easiest for self-administration
• D. Clean the injection site with soap and water and avoid alcohol

Correct answer: C

Rationale: The correct answer is C because the muscles in the abdomen and thigh are the most suitable areas for self-administration of insulin due to consistent absorption. Choices A and B are incorrect as aspirating before injecting insulin is unnecessary, and injecting into an extremity to be exercised does not enhance absorption. Choice D is incorrect as alcohol should be used to clean the injection site instead of soap and water, which can cause skin irritation.

2. 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.

3. In public education on Typhoid fever, the condition mainly spreads through:

• A. Contaminated air
• B. Mineral water
• C. Contaminated food and water
• D. All of the above

Correct answer: C

Rationale: Typhoid fever is primarily spread through contaminated food and water, usually due to poor sanitation practices. The bacteria responsible for typhoid fever, Salmonella Typhi, is typically found in food or water contaminated by the feces of an infected person. Contaminated air is not a significant mode of transmission for typhoid fever, making choice A incorrect. While waterborne transmission can occur, it is through contaminated water rather than specifically mineral water, making choice B incorrect. Therefore, the correct answer is C, as contaminated food and water are the main sources of transmission for typhoid fever.

4. In the pediatric ward at Nyamebekyere teaching hospital, when should oxygen be applied to children?

• A. Central cyanosis
• B. Respiratory rate >70 breaths per minute
• C. Grunting noted on assessment
• D. All of the above

Correct answer: D

Rationale: All the listed conditions, central cyanosis, respiratory rate >70 breaths per minute, and grunting on assessment, are indicative of the need for oxygen therapy. Central cyanosis suggests severe hypoxemia, a respiratory rate >70 breaths per minute can indicate respiratory distress, and grunting is a sign of increased work of breathing. Administering oxygen in these situations can help improve oxygenation and support the child's respiratory function, making option D the correct choice.

5. The word hormone is derived from the Greek 'hormao' meaning 'I excite or arouse'. Hormones communicate this effect by their unique chemical structures recognized by specific receptors on their target cells, by their patterns of secretion, and their concentrations in the general or local circulation. 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: The function of producing new offspring is not attributed to hormones. Hormones primarily regulate various physiological processes in the body such as growth, metabolism, reproduction, and immune response, but they do not directly play a role in producing offspring.
