A patient undergoing mechanical ventilation in the ICU develops ventilator-associated pneumonia (VAP) caused by methicillin-resistant Staphylococcus aureus (MRSA). What intervention should the healthcare team prioritize to manage the patient's infection?

Correct Answer: A

Rationale: The most important intervention for managing ventilator-associated pneumonia (VAP) caused by methicillin-resistant Staphylococcus aureus (MRSA) in a patient undergoing mechanical ventilation in the ICU is to start appropriate antimicrobial therapy targeting MRSA. Vancomycin or linezolid are commonly used antibiotics for MRSA infections. These medications are effective against MRSA and can help in treating the infection and preventing further complications. It is crucial to initiate antimicrobial therapy promptly once the diagnosis of VAP caused by MRSA is suspected or confirmed to improve patient outcomes. Other interventions such as bronchoalveolar lavage for diagnostic purposes, contact precautions, or antifungal therapy may be relevant but the priority is to start effective antibiotic therapy to target the specific pathogen causing the infection.

Correct Answer: A

Rationale: The sudden onset of severe vertigo, nausea, vomiting, and nystagmus in a patient with a recent upper respiratory tract infection is highly suggestive of vestibular neuritis. Vestibular neuritis is typically caused by inflammation of the vestibular nerve, often following a viral infection such as an upper respiratory tract infection. This condition presents with acute, severe, continuous vertigo without associated hearing loss. The presence of nystagmus, along with the absence of hearing loss, helps differentiate vestibular neuritis from Meniere's disease (which typically presents with episodic vertigo, hearing loss, and tinnitus) and acoustic neuroma (which presents with gradual onset of symptoms including unilateral hearing loss, tinnitus, and imbalance). Benign paroxysmal positional vertigo (BPPV) typically presents with brief episodes of vertigo triggered by specific head movements, rather than the continuous vertigo seen in this case.

Correct Answer: D

Rationale: The principle of beneficence emphasizes the duty to do good and act in the best interest of others. By ensuring that all necessary supplies and medicines are available for the care of the community, Nurse Erica is practicing beneficence. She is fulfilling her obligation to promote the health and well-being of the community members by providing them with the resources they need for their care. This demonstrates her commitment to doing good and acting in a way that benefits those under her care, which aligns with the principle of beneficence in nursing practice.

Correct Answer: C

Rationale: Sarah's condition seems to be related to growth and wound healing issues, based on the provided clinical manifestations. Decrease libido is typically unrelated to conditions like edema, poor wound healing, and absence of growth in the pubic area. Therefore, it would not be a complaint stemming from Sarah's condition.

Correct Answer: A

Rationale: Estrogen exerts negative feedback on the hypothalamus by inhibiting the release of GnRH (Gonadotropin-Releasing Hormone). GnRH plays a crucial role in the regulation of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) production from the pituitary gland. By inhibiting the release of GnRH, estrogen ultimately leads to a decrease in FSH and LH levels. This process helps to suppress the maturation of the egg and ovulation, providing contraceptive effects.

Correct Answer: B

Rationale: Health education is a crucial component of public health aimed at promoting health, preventing diseases, and empowering individuals to make informed decisions about their health. It is not limited to only professionals like nurses but is the responsibility of every health worker across various disciplines. Health workers, including doctors, community health workers, public health educators, and others, play a vital role in delivering health education to the community they serve. By ensuring that health education is a shared responsibility among all health workers, a more comprehensive and effective approach to public health promotion can be achieved. It is continuously evolving to adapt to changing health needs and challenges, making it dynamic rather than remaining constant. Therefore, option B is the most accurate statement regarding health education in public health.

Correct Answer: C

Rationale: Placing the client in a left side-lying position after a liver biopsy helps to promote pressure on the puncture site, which can reduce the risk of bleeding. Placing a small pillow or folded towel under the puncture site provides additional support and helps to maintain pressure on the area. This position also helps prevent the client from putting pressure on the abdomen, which could potentially affect the biopsy site and increase the risk of bleeding or complications. Overall, positioning the client on the left side with support under the puncture site is the most appropriate and safest option after a liver biopsy.

Correct Answer: D

Rationale: Patients with hypothyroidism have a decreased ability to regulate their body temperature due to the reduced hormone levels. Exposure to cold temperatures can exacerbate this issue and lead to symptoms such as cold intolerance, feeling cold all the time, and potentially even hypothermia. It is important for patients with hypothyroidism to avoid prolonged exposure to cold temperatures to prevent any negative impact on their health.

Correct Answer: C

Rationale: The patient's presentation of jaundice, ascites, spider angiomas, elevated serum bilirubin levels, prolonged prothrombin time, and hypoalbuminemia are all indicative of cirrhosis. Cirrhosis is a late stage of liver disease characterized by liver scarring and poor liver function. Jaundice, which is the yellowing of the skin and eyes due to elevated bilirubin levels, is a common manifestation of liver dysfunction seen in cirrhosis. Ascites, the accumulation of fluid in the abdomen, is also a common complication of cirrhosis. Spider angiomas, which are small blood vessels near the skin's surface, are a result of altered blood flow in the liver due to cirrhosis. Prolonged prothrombin time and hypoalbuminemia are consequences of reduced liver synthesis function in cirrhosis. Hepatic encephalopathy and hepatorenal syndrome
