1. Generally, patients who wear dentures have reduced masticatory efficiency. Mandibular implant-supported dentures can have positive effects on the clinical aspects of mastication and swallowing.
- A. Both statements are true
- B. Both statements are false
- C. The first statement is true; the second is false
- D. The first statement is false; the second is true
Correct answer: A
Rationale: Both statements are true. Patients who wear dentures typically experience reduced masticatory efficiency. Mandibular implant-supported dentures are known to have positive effects on the clinical aspects of mastication and swallowing, significantly improving chewing function. Option A is correct because both statements align with these facts. Option B is incorrect as both statements are true. Option C is incorrect as the second statement is also true. Option D is incorrect as the first statement is true.
2. During a vaso-occlusive crisis in sickle cell anemia, what action is crucial for a nurse to take?
- A. Administer meperidine for pain.
- B. Apply cold compresses to the child's joints.
- C. Limit the child's fluid intake.
- D. Maintain bed rest for the child.
Correct answer: D
Rationale: During a vaso-occlusive crisis in sickle cell anemia, maintaining bed rest is crucial to reduce oxygen consumption and alleviate pain. Movement can worsen the crisis by increasing sickling of red blood cells, leading to further tissue damage and pain. Bed rest helps to improve blood flow, reduce pain, and promote healing. Administering meperidine for pain (Choice A) is not recommended due to the risk of normeperidine accumulation and potential neurotoxicity. Applying cold compresses (Choice B) may cause vasoconstriction, worsening the vaso-occlusive crisis. Limiting fluid intake (Choice C) is not appropriate as adequate hydration is essential to prevent dehydration and maintain blood flow.
3. What are the final stages of the conflict process?
- A. Antecedent conditions
- B. Perceived and felt conflict
- C. Suppression and resolution
- D. Conflict behavior
Correct answer: C
Rationale: The final stages of the conflict process involve suppression and resolution. After conflicts have been perceived and felt, individuals and parties typically move towards suppressing the conflict (trying to avoid it) and ultimately resolving it. Antecedent conditions refer to factors that exist before conflict arises and do not represent the final stages. Conflict behavior relates to the actions taken during a conflict rather than its final stages.
4. Which of the following is a central vasodilator and peripheral vasoconstrictor?
- A. Sympathetic nervous system
- B. Parasympathetic nervous system
- C. Norepinephrine
- D. Acetylcholine
Correct answer: A
Rationale: The correct answer is the Sympathetic nervous system. The sympathetic nervous system is a branch of the autonomic nervous system that is responsible for the fight-or-flight response. It causes vasodilation in central vessels to increase blood flow to vital organs during stress or exercise, while inducing vasoconstriction in peripheral vessels to redirect blood to essential areas. Norepinephrine and acetylcholine are neurotransmitters associated with the sympathetic and parasympathetic nervous systems, respectively, but they are not themselves central vasodilators and peripheral vasoconstrictors.
5. A nurse is developing a plan of care for a client who will be placed in halo traction following surgical repair of the cervical spine. Which of the following interventions should the nurse include in the plan?
- A. Inspect the pin site every 4 hours
- B. Monitor the client's skin under the halo vest
- C. Ensure two personnel hold the halo device when repositioning the client
- D. Apply powder to the client's skin under the vest to decrease itching
Correct answer: B
Rationale: The correct answer is to monitor the client's skin under the halo vest. This is important to assess for signs of skin issues such as excessive sweating, redness, or blistering, which can lead to skin breakdown and infection. Choice A is incorrect because while inspecting the pin site is important, it should be done more frequently than every 4 hours. Choice C is incorrect as the halo device should be supported by the client's body weight, not personnel, when repositioning. Choice D is incorrect because applying powder frequently can increase the risk of skin irritation and infection.
