Correct Answer: A

Rationale: The correct answer is to instruct the client and their family to check the cord routinely for frays or tearing. This is crucial to ensure the safety and proper function of the oxygen concentrator. Choice B is incorrect because oxygen should never be used around open flames due to the risk of fire. Choice C is also incorrect as oxygen cylinders or concentrators should not be stored in a closet due to ventilation and safety concerns. Choice D is incorrect because synthetic clothing can generate static electricity, which could pose a risk around oxygen equipment.

Correct Answer: C

Rationale: Contact precautions are the appropriate type to use when performing postmortem care for a client with MRSA. MRSA is primarily spread through direct contact, so using contact precautions helps prevent the transmission of the infection. Airborne precautions are not necessary for MRSA, as it is not transmitted through the air like tuberculosis or measles. Droplet precautions are used for diseases transmitted through respiratory droplets like influenza. Compromised host precautions are not a standard precaution type and are not specific to managing MRSA infection.

Correct Answer: A

Rationale: The first step in the nursing process is to obtain information about the client. This step involves gathering data through assessment to understand the client's needs, health status, and preferences. Developing a care plan (Choice B) comes after the assessment phase. Implementing interventions (Choice C) and evaluating client outcomes (Choice D) occur in subsequent stages of the nursing process. Therefore, the correct initial step is to gather information about the client to form a foundation for providing individualized care.

Correct Answer: B

Rationale: The correct answer is B. Rheumatic fever often follows a strep throat infection, which is why the nurse should suspect this association. Strep throat is caused by Group A Streptococcus bacteria, which can trigger an abnormal immune response leading to rheumatic fever. Choices A, C, and D are incorrect because chickenpox, ear infections, and fungal skin infections are not typically associated with rheumatic fever.

Correct Answer: A

Rationale: When a patient reports an inability to clear nasal passages, the appropriate action for the nurse to take is to use gentle suction to prevent tissue damage. Suctioning helps remove excess mucus or secretions without causing harm to the nasal tissues. Instructing the patient to blow their nose forcefully (Choice B) may exacerbate the issue and cause discomfort or injury. Placing a dry washcloth under the nose (Choice C) is not an effective intervention for clearing nasal passages. Inserting a cotton-tipped applicator into the back of the nose (Choice D) is not recommended as it can be invasive and may cause injury or discomfort to the patient.
