A nurse is planning a teaching session for parents of preschool children. Which statement explains why the nurse should include information about morbidity and mortality?
- A. Life span statistics are included in the data.
- B. It explains effectiveness of treatment.
- C. Cost-effective treatment is detailed for the general population.
- D. High-risk age groups for certain disorders or hazards are identified.
Correct Answer: D
Rationale: Including information about morbidity and mortality is important in a teaching session for parents of preschool children because it helps identify high-risk age groups for certain disorders or hazards. By understanding which age groups are more vulnerable to specific health issues, parents can take proactive steps to protect their children and promote their overall well-being. This information also enables parents to recognize signs and symptoms early on, leading to timely interventions and better outcomes for their children's health.

What is the earliest age at which a satisfactory radial pulse can be taken in children?
- A. 1 year
- B. 2 years
- C. 3 years
- D. 6 years
Correct Answer: A
Rationale: A satisfactory radial pulse can be taken in children as young as 1 year old. The radial pulse is commonly checked in the wrist and is a valuable indicator of cardiac function. Children as young as 1 year old can have a palpable radial pulse, allowing healthcare providers to assess their heart rate and rhythm. It is important to be gentle when palpating a pulse in young children to avoid causing discomfort or distress.
which of the following is a characteristic in a child with acute lymphocytic leukemia?
- A. fatigability
- B. persistent fever of unknown cause
- C. tendency to bruise easily
- D. all of the above are correct
Correct Answer: D
Rationale: Children with acute lymphocytic leukemia commonly present with a combination of symptoms which can include fatigability, persistent fever of unknown cause, and a tendency to bruise easily. Fatigue is a common complaint in children with leukemia due to anemia caused by decreased production of healthy red blood cells. Persistent fevers can be a sign of infection, anemia, or other complications related to leukemia. Additionally, children with leukemia may have a low platelet count, leading to easy bruising or bleeding tendencies. Therefore, all of the characteristics mentioned in the options are correct for a child with acute lymphocytic leukemia.
A client with thrombocytopenia secondary to leukemia develops epistaxis. The nurse should instruct the client to:
- A. Lie supine with his neck extended
- B. Sit upright, leaning slightly forward
- C. Blow his nose and then put lateral pressure on his nose
- D. Hold his nose while bending forward at the waist
Correct Answer: B
Rationale: The nurse should instruct the client to sit upright, leaning slightly forward when experiencing epistaxis (nosebleed). This position helps prevent blood from dripping down the back of the throat, reducing the risk of aspiration. In the case of a client with thrombocytopenia secondary to leukemia, the blood may have difficulty clotting due to low platelet counts. Therefore, it is important to minimize bleeding as much as possible. Lying supine with the neck extended may increase the risk of blood flowing down the throat, while blowing the nose or putting lateral pressure on it may aggravate the bleeding. Holding the nose while bending forward at the waist may also increase blood flow towards the head. Sitting upright, leaning slightly forward is the safest position to prevent complications associated with epistaxis in this case.
An elderly nursing home resident who has always been alert and oriented is now showing signs of dehydration and has become confused. Which electrolyte imbalance is most likely involved?
- A. Hyponatremia
- B. Hypercalcemia
- C. Hyperkalemia
- D. Hypomagnesemia
Correct Answer: A
Rationale: Hyponatremia is an electrolyte imbalance characterized by low sodium levels in the blood. Sodium plays a crucial role in regulating the body's fluid balance and is essential for nerve and muscle function. Elderly individuals are at a higher risk of developing hyponatremia due to various factors, including medication use, reduced thirst sensation, and impaired kidney function.
