A nurse is planning teaching for a client and their family about home oxygen therapy. Which of the following information should the nurse plan to include in the teaching?

The correct answer is choice C. Determine the client’s Glasgow Coma Scale score. This is because the Glasgow Coma Scale (GCS) is a tool to assess the level of consciousness and neurological status of a client who has a closed head injury. The GCS score can help guide the priority of interventions and the need for further diagnostic tests.

Choice A is wrong because an MRI of the brain is not the first action to take for a client who has a closed head injury. An MRI may be indicated later to evaluate the extent of brain damage, but it is not an emergency procedure.

Choice B is wrong because mannitol IV bolus is a medication that reduces intracranial pressure (ICP) by drawing fluid out of the brain tissue. However, mannitol should not be administered before confirming the presence and degree of increased ICP, which can be done by measuring the GCS score and other vital signs.

Choice D is wrong because inserting an indwelling urinary catheter for the client is not the first action to take for a client who has a closed head injury. A urinary catheter may be needed to monitor fluid balance and renal function, but it is not an urgent intervention.

The correct answer is choice B. Determine the client’s knowledge about diaphragm use. This is the first action the nurse should take because it allows the nurse to assess the client’s readiness to learn, identify any knowledge gaps, and tailor the teaching to the client’s needs.

Some of the other choices are wrong because:

• Choice A. Supervise return demonstration of diaphragm use.

This is not the first action the nurse should take because it assumes that the client already knows how to use the diaphragm correctly and safely. The nurse should first teach the client how to insert, remove, and care for the diaphragm before asking for a return demonstration.

• Choice C. Document the client’s level of understanding about potential adverse effects.

This is not the first action the nurse should take because it is part of the evaluation phase of teaching, not the assessment phase. The nurse should first determine what the client knows and needs to know about diaphragm use and its possible risks and benefits.

• Choice D. Teach the client how to insert the diaphragm.

This is not the first action the nurse should take because it is part of the implementation phase of teaching, not the assessment phase. The nurse should first assess the client’s knowledge, motivation, and preferences before providing instruction on how to use the diaphragm.

A contraceptive diaphragm is a birth control device that prevents sperm from entering the uterus.

It is a small, soft silicone or rubber cup with a flexible rim that covers the cervix.

It is inserted into the vagina with spermicide before sex and is held in place by the pelvic muscles. It is a reusable type of contraception that women can use to avoid getting pregnant.
