To provide safe care for Mrs. Zeno, it is important for the nurse to check the bedside for the presence of:
- A. A tracheostomy set
- B. A hypothermia blanket
- C. An intravenous set-up
- D. A syringe and edrophonium HCl(Tensilon)
Correct Answer: B
Rationale: Checking the bedside for the presence of a hypothermia blanket is crucial for providing safe care for Mrs. Zeno. Hypothermia blankets are used to prevent or treat hypothermia, which is a condition where the body temperature drops below normal levels. Maintaining normothermia (normal body temperature) is important for the overall well-being of patients, especially those who are at risk of developing complications due to temperature fluctuations. Therefore, having a hypothermia blanket readily available at the bedside ensures that the nurse can promptly address any temperature-related issues to optimize Mrs. Zeno's care and safety.

A 6-year-old child is scheduled for an IV urography (IVP) in the morning. Which preparatory interventions should the nurse plan to implement? (Select all that apply.)
- A. Clear liquids in the morning before the procedure
- B. Cathartic in the evening before the procedure
- C. Soapsuds enema the morning of the procedure
- D. Insertion of a Foley catheter before the procedure
Correct Answer: A
Rationale: Clear liquids in the morning before the procedure: It is important for the child to have clear liquids before the procedure to ensure proper hydration and to help with visualization during the urography.
The nurse teaches a diabetic client that diet plays a crucial role in managing diabetes mellitus. When evaluating dietary intake, the nurse knows the client is eating the right foods if total daily caloric intake consists of:
- A. 30% to 35% carbohydrate, 40% fat, and 25% to 30% protein
- B. 40% to 45% carbohydrate, 40% fat, and 15% to 20% protein
- C. 50% to 55% carbohydrate, 35% fat, and 10% to 15% protein
- D. 55% to 60% carbohydrate, 30% fat and 10% to 15% protein
Correct Answer: A
Rationale: In managing diabetes mellitus, one of the key principles is proper macronutrient distribution in the diet. The recommended dietary intake for a diabetic client typically includes a moderate amount of carbohydrates (30% to 35% of total calories) in order to help control blood sugar levels. Including higher amounts of fat (around 40%) can be beneficial in managing this condition as well. Adequate protein intake (25% to 30%) is also important for overall health and satiety. This balanced macronutrient distribution helps in maintaining stable blood sugar levels throughout the day, supporting optimal diabetes management.
Which is most likely to encourage parents to talk about their feelings related to their child's illness?
- A. Be sympathetic.
- B. Use direct questions.
- C. Use open-ended questions.
- D. Avoid periods of silence.

This approach can help parents feel understood and supported, ultimately fostering more honest and meaningful discussions about their child's illness.
The kidneys regulate acid-base balance by all of the following mechanisms except:
- A. Excreting hydrogen ions (H )
- B. Reabsorbing carbon dioxide into the
- C. Reabsorbing or excreting HCO into blood
- D. retaining hydrogen ions
Correct Answer: B
Rationale: The kidneys help regulate acid-base balance through several mechanisms, including excreting hydrogen ions (H+), reabsorbing or excreting bicarbonate (HCO3-) into the blood, and retaining or excreting hydrogen ions. However, the kidneys do not play a direct role in reabsorbing carbon dioxide into the blood. Carbon dioxide is mainly managed in the body through the respiratory system, where it is exhaled as a waste product of metabolism.
Which of the following types of cells is the immune system's shutoff mechanism?
- A. Plasma cells
- B. Suppressor T cells
- C. Helper T cells
- D. B lymphocytes
Correct Answer: B
Rationale: Suppressor T cells, also known as regulatory T cells, play a critical role in regulating the immune response by acting as the immune system's shutoff mechanism. These cells help maintain immune tolerance and prevent overactivation of the immune system, thereby preventing autoimmune reactions and excessive inflammation. Suppressor T cells exert their immunosuppressive effects by inhibiting the function of other immune cells, such as effector T cells and B cells, and helping to control the overall balance of the immune system.
