Community Health HESI
1. A home health nurse is reviewing the laboratory results for several clients with heart failure. Which client finding would the nurse report to the health care provider immediately?
- A. Total cholesterol 190
- B. Glycosylated hemoglobin of 7%
- C. B-type natriuretic peptide 550 pg/ml (more than 100 is concerning)
- D. Potassium 3.7
Correct answer: C
Rationale: An elevated B-type natriuretic peptide level indicates worsening heart failure, requiring immediate attention. This biomarker reflects the severity of heart failure and helps guide treatment decisions. Total cholesterol and glycosylated hemoglobin are important for assessing cardiovascular risk and diabetes management but are not indicative of acute heart failure exacerbation. A potassium level of 3.7 falls within the normal range and does not suggest an immediate concern in the context of heart failure.
2. When developing a presentation on injury prevention for high school students in a health education class, which topic is most important for the nurse to include?
- A. Sports-related injuries
- B. Substance abuse
- C. Seat belt safety
- D. Pregnancy prevention
Correct answer: C
Rationale: The correct answer is C: Seat belt safety. This topic is crucial as it can significantly reduce the risk of injury or death in car accidents, which is a common cause of severe injuries among high school students. While sports-related injuries, substance abuse, and pregnancy prevention are important topics, seat belt safety directly addresses a preventable cause of injuries that can have immediate life-saving effects.
3. During a well-child visit for their child, one of the parents with an autosomal dominant disorder tells the nurse, 'We don’t plan on having any more children, since the next child is likely to inherit this disorder.' How should the nurse respond?
- A. Explain that the risk of inheriting the disorder decreases by 50% with each child the couple has.
- B. Acknowledge that the next child will inherit the disorder since the first child did not.
- C. Encourage the couple to reconsider their decision since the inheritance pattern may be sex-linked.
- D. Confirm that there is a 50% chance of their future children inheriting the disorder.
Correct answer: D
Rationale: Confirming that there is a 50% chance of their future children inheriting the disorder is the correct response in this situation. Autosomal dominant disorders have a 50% chance of being passed on to each child. Providing accurate genetic counseling is essential to help the parents make informed decisions about family planning. Choices A, B, and C are incorrect. Choice A is inaccurate because the risk of inheriting an autosomal dominant disorder remains at 50% for each child regardless of the number of children the couple has. Choice B is not appropriate as it does not provide helpful information or support to the parents. Choice C is misleading because autosomal dominant disorders follow a specific inheritance pattern and are not sex-linked.
4. A healthcare professional prepares to administer sodium polystyrene sulfonate (Kayexalate) to a client. Before administering the medication, the professional reviews the action of the medication and understands that it:
- A. Releases bicarbonate in exchange for primarily sodium ions
- B. Releases sodium ions in exchange for primarily potassium ions
- C. Releases potassium ions in exchange for primarily sodium ions
- D. Releases sodium ions in exchange for primarily bicarbonate ions
Correct answer: B
Rationale: Sodium polystyrene sulfonate, such as Kayexalate, is a cation exchange resin that functions by releasing sodium ions in exchange for primarily potassium ions. This medication is commonly used to treat hyperkalemia, a condition characterized by elevated levels of potassium in the blood.
5. The nurse is caring for a client who has a chest tube in place following a pneumothorax. The nurse notes that there is continuous bubbling in the water seal chamber of the chest tube drainage system. What action should the nurse take?
- A. Check for kinks in the tubing
- B. Notify the healthcare provider
- C. Replace the chest tube drainage system
- D. Reinforce the chest tube dressing
Correct answer: B
Rationale: The correct action for the nurse to take when observing continuous bubbling in the water seal chamber of the chest tube drainage system is to notify the healthcare provider. Continuous bubbling indicates a possible air leak, and the healthcare provider needs to be informed to assess the situation and take appropriate actions. Checking for kinks in the tubing (Choice A) may be done initially but is not the priority when continuous bubbling is present. Replacing the chest tube drainage system (Choice C) and reinforcing the chest tube dressing (Choice D) are not immediate actions needed in response to continuous bubbling in the water seal chamber.
