1. Which information about hemophilia will the nurse include in the teaching plan for the parents of a child diagnosed with hemophilia?
- A. Autosomal dominant disorder in which the blood clotting factors are deficient.
- B. X-linked recessive inherited disorder in which blood clotting factors are deficient.
- C. X-linked recessive inherited disorder involving decreased platelets causing prolonged bleeding.
- D. Autosomal recessive disorder in which the blood clotting factors are deficient.
Correct answer: B
Rationale: The correct answer is B: Hemophilia is an X-linked recessive disorder, primarily affecting males and passed from mothers to sons. It involves a deficiency in clotting factors, leading to prolonged bleeding. Choice A is incorrect as hemophilia is not autosomal dominant. Choice C is incorrect as hemophilia does not involve platelets. Choice D is incorrect as hemophilia is not autosomal recessive.
2. Which heart sound is produced by vibrations within the heart chambers or in the major arteries from the back-and-forth flow of blood?
- A. S1 and S2
- B. S3 and S4
- C. Murmur
- D. Physiologic splitting
Correct answer: C
Rationale: A murmur is produced by turbulent blood flow within the heart or major arteries, resulting in audible vibrations.
3. A child with pyloric stenosis is having excessive vomiting. The nurse should assess for what potential complication?
- A. Hyperkalemia
- B. Hyperchloremia
- C. Metabolic acidosis
- D. Metabolic alkalosis
Correct answer: D
Rationale: Excessive vomiting in pyloric stenosis leads to the loss of stomach acid (hydrochloric acid), resulting in metabolic alkalosis, not hyperkalemia, hyperchloremia, or metabolic acidosis. Metabolic alkalosis is characterized by a higher pH level in the blood due to the loss of acid and a relative increase in bicarbonate. Hyperkalemia is an elevated level of potassium in the blood and is not directly related to excessive vomiting in pyloric stenosis. Hyperchloremia is an excess of chloride in the blood, which is not typically associated with this condition. Metabolic acidosis is a condition characterized by a lower pH level in the blood, caused by an excess of acid or a loss of bicarbonate, which is not the typical complication seen in pyloric stenosis with excessive vomiting.
4. A mother tells the nurse that she does not want her infant immunized because of the discomfort associated with injections. What should the nurse explain?
- A. This cannot be prevented
- B. Infants do not feel pain as adults do
- C. This is not a good reason for refusing
- D. A topical anesthetic can be applied
Correct answer: D
Rationale: The nurse should explain that a topical anesthetic can be applied to the injection site before the immunization to reduce discomfort.
5. What is the most effective method to prevent infection in the newborn?
- A. Using disposable items
- B. Practicing proper hand hygiene by staff and family
- C. Administering prophylactic antibiotics
- D. Isolating the newborn from others
Correct answer: B
Rationale: The most effective method to prevent infection in newborns is by practicing proper hand hygiene by staff and family. This is crucial as it helps reduce the transmission of infectious agents, protecting vulnerable newborns. Using disposable items may help, but proper hand hygiene is more effective. Administering prophylactic antibiotics without a specific indication can lead to antibiotic resistance and is not recommended. Isolating the newborn from others is not practical and may not be necessary if proper hand hygiene is maintained.
