Correct Answer: B

Rationale: Systematic meta-analysis of the literature typically involves synthesizing research findings from multiple studies on a particular topic. The most common way to gather relevant studies for a meta-analysis is by searching through electronic databases. These databases contain a wide range of peer-reviewed literature such as research articles, reviews, and conference papers. Using electronic databases ensures a comprehensive and systematic approach to finding all relevant studies needed for a meta-analysis. While doctoral dissertations and statistical methods such as those offered by Cochrane can also be valuable sources of information, an electronic database is the primary tool used for conducting a systematic meta-analysis of the literature.

Correct Answer: B

Rationale: Clozapine is an atypical antipsychotic medication primarily used in the treatment of schizophrenia. One of the positive effects of Clozapine is the reduction of psychotic symptoms experienced by the patient, such as hallucinations (not hearing loss). Clozapine is effective in managing both positive symptoms (hallucinations, delusions, disorganized thinking) and negative symptoms (apathy, social withdrawal, lack of motivation) of schizophrenia. It is known for its efficacy in reducing hallucinations and other psychotic symptoms, helping the patient to lead a more stable and functional life.

Correct Answer: A

Rationale: Administering systemic analgesia, such as pain medications or anesthesia, before the wound debridement procedure is the most effective way to minimize patient discomfort. These medications will help manage and reduce the pain experienced by the patient during the procedure, making it more tolerable for them. Topical anesthetic cream may provide some localized relief but may not be sufficient for significant pain management during a wound debridement procedure. Using sharp debridement techniques or performing the procedure quickly may help reduce manipulation or duration, respectively, but these actions alone may not adequately address the patient's pain and discomfort. Administering systemic analgesia ensures that the patient's overall pain is managed, promoting a more comfortable and successful wound debridement procedure.

Correct Answer: B

Rationale: When a patient is in skin traction, the constant pressure and rubbing against the skin from the traction device can lead to skin breakdown. Therefore, assessing for signs of skin breakdown, such as redness, irritation, or pressure injuries, is crucial to prevent complications and ensure the patient's comfort and safety. Prompt identification and intervention for any skin issues can prevent further damage and promote healing, making this the priority intervention for quality nursing care in skin traction. While monitoring for signs of infection, urinary incontinence, and bowel sounds are important, skin breakdown poses a more immediate threat to the patient's well-being in this scenario.

Correct Answer: C

Rationale: The submandibular gland is located inferior and posterior to the mandible. It produces a mixed type of saliva, which is primarily serous (enzyme-rich) but also contains some mucous components. This gland plays a significant role in digestion, as its serous saliva contains enzymes such as amylase that help break down carbohydrates in the mouth before they reach the stomach.
