Community Health HESI Study Guide
1. The nurse is assessing a 12-year-old who has Hemophilia A. Which finding would the nurse anticipate?
- A. An excess of red blood cells
- B. An excess of white blood cells
- C. A deficiency of clotting factor VIII
- D. A deficiency of clotting factors VIII and IX
Correct answer: C
Rationale: The correct answer is C: A deficiency of clotting factor VIII. Hemophilia A is characterized by a lack of clotting factor VIII, which is crucial for blood clotting. This deficiency results in prolonged bleeding. Choices A, B, and D are incorrect. There is no association between Hemophilia A and an excess of red blood cells (Choice A) or an excess of white blood cells (Choice B). Additionally, Hemophilia A specifically involves a deficiency of clotting factor VIII, not both factors VIII and IX (Choice D).
2. A female client on the psychiatric unit tells the nurse that she feels like ending her life because she can no longer deal with her depression. What is the nurse's priority intervention?
- A. Stay with the client and ensure her safety.
- B. Inform the client that she is safe in the hospital.
- C. Document the client's statements in her medical record.
- D. Encourage the client to join a group therapy session.
Correct answer: A
Rationale: The correct answer is to stay with the client and ensure her safety. Ensuring the client's safety is the top priority when a client expresses suicidal ideation. Staying with the client can help prevent self-harm while further assessment and interventions are arranged. Choice B is incorrect because simply informing the client that she is safe in the hospital does not address the immediate need for safety. Choice C is incorrect as while documentation is important, it is not the priority when a client's safety is at risk. Choice D is also incorrect as encouraging the client to join a group therapy session is not appropriate when the client is in crisis and expressing suicidal thoughts.
3. What is the most common cause of shock (hypoperfusion) in infants and children?
- A. infection
- B. cardiac failure
- C. accidental poisoning
- D. severe allergic reaction
Correct answer: A
Rationale: Infection is the leading cause of shock in infants and children due to their heightened vulnerability to sepsis. Infants and children possess developing immune systems, rendering them more susceptible to infections that can progress to septic shock. While cardiac failure is a severe condition, it is not as commonly the primary cause of shock in this age group. Accidental poisoning, though a potential shock inducer, is less prevalent in infants and children compared to infections. Severe allergic reactions, though significant, are not as frequent as infections in precipitating shock in infants and children.
4. The client is being taught about the use of syringes and needles for home administration of medications. Which action by the client indicates an understanding of standard precautions?
- A. Remove the needle after discarding used syringes
- B. Wear gloves while disposing of the needle and syringe
- C. Wear a face mask during medication administration
- D. Wash hands before handling the needle and syringe
Correct answer: D
Rationale: The correct answer is D. Washing hands before handling the needle and syringe is a critical step in infection control and adherence to standard precautions. Clean hands help prevent the transfer of microorganisms and reduce the risk of infection. Choices A, B, and C do not directly relate to standard precautions. Removing the needle after discarding used syringes (Choice A) can increase the risk of needlestick injuries. Wearing gloves while disposing of the needle and syringe (Choice B) is important for personal protection but does not specifically address standard precautions. Wearing a face mask during medication administration (Choice C) is not directly related to handling syringes and needles, which are more pertinent to standard precautions.
5. During a routine monthly examination, a 5-month-old infant is brought to the pediatric clinic. What assessment finding should alert the nurse to notify the health care provider immediately?
- A. Temperature of 99.5°F
- B. Blood pressure of 75/48 mm Hg
- C. Heart rate of 100 beats per minute
- D. Respiratory rate of 50 breaths per minute
Correct answer: D
Rationale: A respiratory rate of 50 breaths per minute in a 5-month-old infant is higher than the expected range and may indicate respiratory distress. This finding is concerning and should prompt the nurse to notify the health care provider for further evaluation and intervention. A temperature of 99.5°F, blood pressure of 75/48 mm Hg, and heart rate of 100 beats per minute are within normal ranges for a 5-month-old infant. Elevated temperature may indicate a mild fever, which can be monitored. A blood pressure of 75/48 mm Hg is within the normal range for infants. A heart rate of 100 beats per minute is also within the expected range for a 5-month-old infant and does not typically require immediate notification of the health care provider.
