A patient presents with sudden-onset severe headache, nausea, vomiting, and photophobia. On examination, there is neck stiffness and positive Kernig and Brudzinski signs. Which of the following neurological conditions is most likely responsible for these symptoms?

Correct Answer: A

Rationale: The symptoms described - sudden-onset severe headache, nausea, vomiting, photophobia, neck stiffness, and positive Kernig and Brudzinski signs - are classic manifestations of meningitis. Meningitis is an inflammation of the meninges, the protective membranes covering the brain and spinal cord, often caused by infection. The sudden onset of these symptoms and signs, along with neck stiffness and positive Kernig and Brudzinski signs (indicative of meningeal irritation), strongly suggest meningitis as the most likely diagnosis in this scenario.

Correct Answer: C

Rationale: Delegation by succession is the act of assigning a specific task or responsibility to someone temporarily while the usual person in charge is absent or unavailable. In this scenario, the unit manager is delegating her responsibilities to her assistant unit manager while she is on leave, indicating a temporary transfer of duties. This allows for a smooth continuity of operations within the unit during the manager's absence.

Correct Answer: A

Rationale: The nurse recommends regular monitoring of the patient's blood cholesterol levels to prevent complications from their heart disease. High levels of cholesterol can lead to the buildup of plaque in the arteries, increasing the risk of heart problems such as heart attacks and strokes. Monitoring cholesterol levels allows healthcare providers to assess the patient's risk and make appropriate recommendations for managing their heart disease. Regular monitoring can help track the effectiveness of lifestyle changes or medications in lowering cholesterol levels and reducing the risk of complications.

Correct Answer: A

Rationale: The described presentation of a pruritic, annular rash with central clearing and a raised, scaly border that spreads outward in a centrifugal pattern is characteristic of tinea corporis, commonly known as ringworm. This fungal infection affects the skin and is typically ring-shaped, with a well-defined, slightly raised, and scaly border. The central area often clears as the lesion enlarges peripherally, resembling a ring. It is important to note that ringworm is not caused by a worm but by a fungus. Treatment typically involves antifungal medications applied topically or taken orally, depending on the severity of the infection.

Correct Answer: C

Rationale: Checking the humidifier's water regularly is the priority precautionary measure that should be done by the nurse during oxygen therapy. Maintaining adequate water in the humidifier ensures proper humidification of the oxygen delivered to the patient, helping prevent mucous membrane dryness and irritation. Dry mucous membranes can lead to discomfort, increased risk of infection, and potential damage to the respiratory system. Therefore, ensuring the humidifier's water level is appropriate is crucial for the safety and well-being of the patient receiving oxygen therapy. Limiting visitors, attaching "No Smoking" signage, and connecting the bait to the oxygen tank are important precautions as well, but checking the humidifier's water is the priority measure in this scenario.

Correct Answer: A

Rationale: Patients with nephrotic syndrome who are ordered corticosteroids need to avoid close contact with individuals who have infections or illnesses, as corticosteroids can suppress the immune system and increase the risk of infections. Therefore, it is important to prioritize the safety and well-being of the patient by minimizing potential sources of infection. While diabetes itself does not pose a direct risk to the patient with nephrotic syndrome, individuals with diabetes may have a compromised immune system or be at higher risk for infections, which could potentially be transmitted to the patient. This precaution helps to minimize the risk of infection and maximize the effectiveness of the treatment for nephrotic syndrome.

Correct Answer: B

Rationale: The most appropriate intervention for a patient with difficulty swallowing due to end-stage ALS and concerns about choking is to refer the patient to a speech therapist for swallowing exercises and techniques (Choice B). Speech therapists are trained to assess and manage swallowing difficulties in patients, especially those with neurodegenerative diseases like ALS. They can provide specific exercises and strategies to help the patient swallow safely and reduce the risk of choking. This intervention focuses on addressing the underlying issue causing the difficulty swallowing and aims to improve the patient's quality of life by enhancing their ability to eat and drink. The other options are not as effective or appropriate in addressing the patient's concerns.

Correct Answer: C

Rationale: Clients undergoing nasogastric suctioning are at highest risk for developing metabolic imbalances, specifically metabolic acidosis. Nasogastric suctioning can lead to the loss of gastric acid, which in turn can cause metabolic acidosis due to a decrease in bicarbonate levels in the body. This disruption in the acid-base balance can result in symptoms such as confusion, headache, and overall malaise. It is crucial for the nurse to monitor the client's acid-base status closely and provide appropriate interventions to prevent or correct metabolic acidosis.

Correct Answer: D

Rationale: Scabies is caused by an infestation of the microscopic mite Sarcoptes scabiei. This parasitic mite burrows into the upper layer of the skin, where it lays eggs and causes intense itching and skin irritation. The transmission of scabies usually occurs through close and prolonged skin-to-skin contact with an infested person. Unlike viruses, bacteria, and fungi, which are microorganisms that can also cause skin infections, scabies specifically refers to an infestation by a parasitic mite.
