Which statement best describes direct contact as a mode of pathogen transmission?
- A. Transmission through large aerosols produced by sneezing or coughing
- B. Transfer of an infectious agent by suspended air particles from a reservoir to a host
- C. Transmission of infectious agents carried by dust
- D. Transmission through skin-to-skin contact or body fluids
Correct Answer: D
Rationale: Direct contact transmission occurs when pathogens are spread through skin-to-skin contact or body fluids. This mode of transmission includes activities like touching, kissing, or sexual contact where infectious agents can pass directly from one person to another. It does not involve large aerosols, suspended air particles, or dust as carriers of the pathogen.

When educating the mother of a child with respiratory disease who needs a lot of fluids, the mother tells the nurse that when she offers her 24-month-old son juice, he always shakes his head and says, 'No'. The nurse suggests that the mother:
- A. Be firm and hand him the glass
- B. Distract him with some food
- C. Let him see that he is making her angry
- D. Offer him a choice of two things to drink
Correct Answer: D
Rationale: Offering a choice can help the child feel more in control and willing to drink. By providing the child with options, the mother empowers him to make a decision, which can increase his willingness to drink fluids. This approach promotes a sense of autonomy and may lead to a more positive response from the child, ultimately contributing to better fluid intake, especially important for a child with a respiratory disease.
The parents of a child hospitalized with asthma who is recovering and is being prepared for discharge are receiving home care instructions from the nurse. Which statement by a parent indicates a need for further instruction?
- A. Coughing spells may be triggered by dust or smoke
- B. Vomiting may occur when our child has coughing episodes
- C. We need to encourage our child to drink fluids
- D. We need to maintain droplet precautions and a quiet environment for at least 2 weeks
Correct Answer: D
Rationale: The statement 'We need to maintain droplet precautions and a quiet environment for at least 2 weeks' indicates a need for further instruction. Asthma management does not typically require maintaining droplet precautions. The focus should be on environmental control, medication adherence, and monitoring symptoms rather than droplet precautions, which are more relevant for contagious respiratory infections.
A child with type 1 diabetes mellitus is brought to the emergency department by the mother, who states that the child has been complaining of abdominal pain and has been lethargic. Diabetic ketoacidosis is diagnosed. Anticipating the plan of care, the nurse prepares to administer which type of intravenous (IV) infusion?
- A. 5% dextrose infusion
- B. Normal saline infusion
- C. NPH insulin infusion
- D. Potassium infusion
Correct Answer: B
Rationale: In the management of diabetic ketoacidosis (DKA), the initial intravenous (IV) fluid of choice is normal saline infusion. Normal saline helps to correct dehydration and electrolyte imbalances commonly seen in DKA patients. It does not contain glucose to prevent worsening hyperglycemia or ketoacidosis. NPH insulin infusion is not the initial treatment for DKA; it is typically used after fluid resuscitation. Potassium infusion may be required in DKA to address electrolyte imbalances, but normal saline is the priority for fluid resuscitation.
