Community Health HESI
1. Community health nurses are particularly concerned with the source of communicable diseases such as hepatitis A. Which group of individuals have a higher risk of contracting that type of hepatitis?
- A. IV drug users who share needles
- B. low-income families living in cramped quarters
- C. those who have recently received a blood transfusion
- D. sexually active persons with multiple partners
Correct answer: B
Rationale: The correct answer is B. Hepatitis A is often spread through close personal contact and poor sanitary conditions, which are more common in low-income, cramped living situations. IV drug users sharing needles are at higher risk of hepatitis B and C due to bloodborne transmission. Those who have recently received a blood transfusion are at risk of hepatitis C or other bloodborne infections. Sexually active persons with multiple partners are at risk of hepatitis B, which can be transmitted through sexual contact.
2. The cellular membrane contributes to all except which of the following?
- A. Cell energy production
- B. Cell permeability
- C. Cell communication
- D. Cell protection
Correct answer: A
Rationale: The cellular membrane is involved in regulating cell permeability, communication, and protection. However, it is not directly involved in energy production. Choice A is the correct answer because the cellular membrane does not produce energy; instead, it regulates the passage of molecules in and out of the cell. Choices B, C, and D are incorrect because the cell membrane plays key roles in controlling what enters and exits the cell, facilitating communication between cells, and providing structural support and protection to the cell.
3. A client with diabetic ketoacidosis (DKA) is receiving an insulin infusion. Which finding indicates that the treatment is effective?
- A. Potassium level of 4.0 mEq/L.
- B. Blood glucose level of 180 mg/dL.
- C. Urine output of 50 mL/hour.
- D. Absence of ketones in the urine.
Correct answer: D
Rationale: The correct answer is D: Absence of ketones in the urine. In a client with diabetic ketoacidosis (DKA) receiving an insulin infusion, the absence of ketones in the urine indicates that ketoacidosis is resolving. This is a crucial finding as it shows that the insulin therapy is effectively addressing the metabolic imbalance causing DKA. Choices A, B, and C are incorrect: A potassium level of 4.0 mEq/L is within normal range but does not directly reflect the resolution of DKA; a blood glucose level of 180 mg/dL, while improved, is still high and does not specifically indicate the resolution of ketoacidosis; urine output of 50 mL/hour is within normal limits but does not directly point to the resolution of DKA.
4. Which of the following describes an effective method of communication?
- A. A unit manager meets with a new nurse to discuss what is going well and areas for improvement.
- B. A unit manager meets with a new nurse to explain departmental policies.
- C. A unit manager meets with staff after several safety events to introduce new policies aimed at preventing further safety events.
- D. A unit manager describes safety events that have occurred on the unit to another nurse manager and discusses ideas for policy improvement with the other manager.
Correct answer: A
Rationale: Choice A is the correct answer because it describes an effective method of communication where a unit manager meets with a new nurse to discuss what is going well and areas for improvement. This approach fosters open dialogue, provides constructive feedback, and promotes professional growth. Choice B is incorrect as it only involves the explanation of departmental policies without engaging in a two-way communication process. Choice C is incorrect as it focuses on policy introduction after safety events rather than individual feedback. Choice D is incorrect as it involves discussing safety events with another manager and policy improvement, but it does not directly address individual performance feedback, which is essential for effective communication and professional development.
5. A nurse reviews laboratory results for a client with glomerulonephritis. The client’s glomerular filtration rate (GFR) is 40 mL/min as measured by a 24-hour creatinine clearance. How should the nurse interpret this finding? (Select all that apply.)
- A. Excessive GFR
- B. Reduced GFR
- C. Fluid retention and risks for hypertension
- D. Pulmonary edema
Correct answer: B
Rationale: A GFR of 40 mL/min indicates a reduced glomerular filtration rate. In a healthy adult, the normal GFR ranges between 100 and 120 mL/min. A GFR of 40 mL/min signifies a significant reduction, leading to fluid retention and risks for hypertension and pulmonary edema due to excess vascular fluid. Choices A, C, and D are incorrect. Choice A is incorrect as a GFR of 40 mL/min is not excessive but rather reduced. Choices C and D do not directly address the interpretation of GFR but instead describe potential consequences of a reduced GFR.
