1. An occupational health nurse in a factory is planning interventions to reduce environmental stressors for employees. Which of the following interventions should the nurse use to affect physical agents in the environment?
- A. Teach workers to choose personal strategies to cope with work stress
- B. Limit the amount of time workers spend in temperatures over 43.3°C (110°F)
- C. Provide ear plugs for use at workstations throughout the factory
- D. Obtain dosimeters for employees to wear when using new machinery that emits radiation
Correct answer: B
Rationale: Limiting exposure to extreme temperatures is important to protect workers from heat-related illnesses.
2. Multiple sclerosis manifests as asymmetrical and in different parts of the body because:
- A. Autoreactive lymphocytes are causing diffuse patchy damage to the myelin sheath in the central nervous system.
- B. Acetylcholine receptors are destroyed by immunoglobulin G.
- C. Autoreactive T lymphocytes cause progressive loss of neurons in the substantia nigra.
- D. Cortical motor cells degenerate.
Correct answer: A
Rationale: The correct answer is A. Multiple sclerosis is characterized by the immune system attacking the myelin sheath in the central nervous system. This attack leads to patchy damage on the myelin sheath, resulting in asymmetrical neurological symptoms. Choices B, C, and D are incorrect because they do not accurately describe the pathophysiology of multiple sclerosis. In multiple sclerosis, it is the autoreactive lymphocytes that target and damage the myelin sheath, not acetylcholine receptors, T lymphocytes, or cortical motor cells.
3. A patient has been diagnosed with cytomegalovirus (CMV). Which of the following drugs would be ineffective in the treatment of this disease?
- A. Ribavirin (Rebetol)
- B. Ganciclovir (Cytovene) IV
- C. Foscarnet (Foscavir) IV
- D. Valganciclovir hydrochloride (Valcyte)
Correct answer: A
Rationale: The correct answer is A, Ribavirin (Rebetol). Ribavirin is not effective against CMV. Choice B, Ganciclovir (Cytovene) IV, is a common treatment for CMV as it inhibits viral DNA synthesis. Choice C, Foscarnet (Foscavir) IV, is also used for CMV infections by blocking viral DNA polymerase. Choice D, Valganciclovir hydrochloride (Valcyte), is a prodrug of Ganciclovir and is effective against CMV. Therefore, Ribavirin is the drug that would be ineffective in treating CMV.
4. A nurse is planning eating strategies with a client who has nausea from equilibrium imbalance. Which of the following strategies should the nurse recommend?
- A. Encourage the client to eat even if nauseated.
- B. Provide low-fat carbohydrates with meals.
- C. Limit fluid intake between meals.
- D. Serve hot foods at mealtime.
Correct answer: B
Rationale: Providing low-fat carbohydrates with meals can help manage nausea without overloading the digestive system.
5. An experimental design __________.
- A. allows researchers to gather information in natural life circumstances without altering the participants' experiences
- B. looks at relationships between participants' characteristics and their behavior or development
- C. permits inferences about cause and effect because researchers evenhandedly assign people to treatment conditions
- D. has one major limitation: researchers cannot infer cause and effect
Correct answer: C
Rationale: An experimental design permits inferences about cause and effect because researchers evenhandedly assign people to treatment conditions. This means that researchers can manipulate certain variables and observe the effects on participants, allowing them to determine causation between variables. This is a key strength of experimental research designs. Choices A, B, and D are incorrect because they do not accurately describe the primary purpose or strength of experimental designs. Experimental designs do not focus on gathering information in natural life circumstances (A), looking at relationships between characteristics and behavior (B), or have the limitation of not being able to infer cause and effect (D).
