Community Health HESI
1. The nurse is assessing a client with pneumonia. Which finding requires immediate intervention?
- A. Temperature of 99°F (37.2°C).
- B. Respiratory rate of 20 breaths per minute.
- C. Heart rate of 90 beats per minute.
- D. Fatigue.
Correct answer: C
Rationale: In a client with pneumonia, a heart rate of 90 beats per minute requires immediate intervention. Jugular vein distention indicates increased central venous pressure, suggesting possible complications like heart failure or fluid overload. Monitoring the heart rate closely and addressing any signs of heart failure promptly are crucial. A temperature of 99°F is within normal range and does not require immediate intervention. A respiratory rate of 20 breaths per minute is also normal. Fatigue is a common symptom in pneumonia but does not indicate an immediate need for intervention compared to the critical nature of jugular vein distention.
2. A child is diagnosed with acquired aplastic anemia. The nurse knows that this child has the best prognosis with which treatment regimen?
- A. blood transfusion
- B. chemotherapy
- C. bone marrow transplantation
- D. immunosuppressive therapy
Correct answer: C
Rationale: In the case of acquired aplastic anemia, bone marrow transplantation offers the best chance of cure as it replaces the abnormal stem cells with healthy ones. Blood transfusion may provide temporary relief by replacing blood cells, but it does not address the root cause of the condition. Chemotherapy may be used in some cases, but it is not the preferred treatment for acquired aplastic anemia. While immunosuppressive therapy can be effective, especially in patients who are not candidates for a bone marrow transplant, it is not the first-line treatment and does not offer the same potential for a cure as bone marrow transplantation.
3. A client with heart disease is on a continuous telemetry monitor and has developed sinus bradycardia. In determining the possible cause of the bradycardia, the nurse assesses the client's medication record. Which medication is most likely the cause of the bradycardia?
- A. Propranolol (Inderal).
- B. Captopril (Capoten).
- C. Furosemide (Lasix).
- D. Dobutamine (Dobutrex).
Correct answer: A
Rationale: Propranolol (Inderal) is a beta-adrenergic blocking agent that acts to decrease heart rate and contractility. Sinus bradycardia is a common side effect of beta blockers due to their negative chronotropic effect on the heart. Captopril (Capoten) is an ACE inhibitor used for hypertension and heart failure, not associated with causing bradycardia. Furosemide (Lasix) is a loop diuretic that can lead to electrolyte imbalances but not commonly linked to bradycardia. Dobutamine (Dobutrex) is a beta-1 adrenergic agonist that increases heart rate and contractility, making it an unlikely cause of bradycardia in this scenario.
4. The community health nurse believes that immunization rates in a lower socioeconomic section of the city are probably below the target set by the state health department. What action should the nurse take first to intervene with this health problem?
- A. join a political action group that focuses attention on the issue in the local news media
- B. partner with a local children's hospital in setting up free 'shot' clinics in the neighborhood
- C. review current epidemiological population data that might document a low immunization rate
- D. call a meeting of citizens to inform them of the importance of having their children immunized
Correct answer: C
Rationale: The most appropriate initial action for the community health nurse to take when addressing low immunization rates in a lower socioeconomic area is to review current epidemiological data. By reviewing this data, the nurse can gather evidence that documents the low immunization rate in the community. This information is crucial to support the need for targeted interventions to increase immunization rates. Choices A, B, and D involve actions that may be important at later stages of intervention but are not the first step. Joining a political action group, partnering with a hospital for clinics, or holding a community meeting are all valuable strategies, but they should be based on evidence obtained from reviewing epidemiological data to ensure targeted and effective interventions.
5. What is the smallest and most basic unit of matter?
- A. Micromolecule
- B. Atom
- C. Organelle
- D. Molecule
Correct answer: B
Rationale: The correct answer is B, Atom. An atom is the smallest unit of matter that retains the properties of an element. Choice A, Micromolecule, is incorrect because molecules are composed of atoms bonded together, making them larger than individual atoms. Choice C, Organelle, is incorrect as organelles are structures within cells, not the basic unit of matter. Choice D, Molecule, is incorrect as molecules are made up of atoms bonded together, so they are not the smallest unit of matter.
