HESI Fundamentals 2023 Quizlet

Correct Answer: B

Rationale: In a normal sitting position, both feet should be supported on the floor with the ankles comfortably flexed. This position helps in maintaining stability and proper alignment. Choice A is incorrect because the edge of the seat pressing against the popliteal space may cause discomfort and is not indicative of proper alignment. Choice C is incorrect as the body weight should be evenly distributed for proper alignment and comfort, not solely on the buttocks. Choice D is incorrect as the position of the arms alone does not indicate proper body alignment in the sitting position; proper arm positioning is important for comfort but not a key indicator of body alignment.

Correct Answer: C

Rationale: The correct intervention for an employee exposed to an unknown dry chemical is to brush off the chemical from the skin and clothing. This helps prevent further skin contact before irrigation can be done. Irrigating the affected area with running water is crucial after brushing off the chemical to minimize the exposure. Washing the affected area with antibacterial soap is not appropriate for chemical burns, as soap can react with certain chemicals and worsen the situation. Leaving the clothing in place until emergency personnel arrive may allow the chemical to continue to harm the skin and should be avoided.

Correct Answer: A

Rationale: The correct instruction for the nurse to give the client who is starting on antihypertensive medication is to 'Get up and change positions slowly.' Antihypertensive medications can cause orthostatic hypotension, a drop in blood pressure when changing positions, so changing positions slowly helps prevent this adverse effect. Choice B about avoiding aged cheese and smoked meat is more relevant for clients taking monoamine oxidase inhibitors (MAOIs) due to potential interactions. Choice C regarding reporting unusual bruising or bleeding is more applicable for clients on anticoagulants. Choice D about consuming consistent amounts of vitamin K-containing foods daily is important for clients taking warfarin, not antihypertensive medications.

Correct Answer: B

Rationale: In a fire emergency, the nurse's priority is to activate the fire alarm. This action alerts others to the emergency, initiates the evacuation process, and ensures everyone's safety. Extinguishing the fire can be dangerous and should be left to trained personnel. Moving clients who are nearby might delay the activation of the alarm and can put the nurse and clients at risk. Closing all open doors on the unit is important to contain the fire but should not take precedence over alerting others through the fire alarm system.

Correct Answer: B

Rationale: The ventrogluteal site is the most appropriate site for administering an intramuscular injection to an adult client. This site is preferred due to its large muscle mass and distance from major nerves and blood vessels, reducing the risk of injury or complications. The deltoid muscle, while commonly used for vaccinations, may not be suitable for certain medications due to its smaller muscle mass. The dorsogluteal site is no longer recommended due to the proximity of the sciatic nerve, which can lead to complications. The rectus femoris site is not commonly used for intramuscular injections in clinical practice.
