Adult Health 2 Exam 1

Correct Answer: D

Rationale: A restless client biting the endotracheal tube can increase airway resistance, triggering the high-pressure alarm and indicating a need for immediate intervention. This behavior can lead to complications such as dislodgement of the tube or airway obstruction. Endotracheal cuff pressure greater than 25 cm H2O, decreased lung compliance, and bilateral crackles with increased secretions are important assessments but do not directly address the urgent need to intervene when a high-pressure alarm is triggered.

Correct Answer: A

Rationale: Corrected Rationale: Monitoring the phenytoin level is crucial to ensure it is within the therapeutic range and to prevent toxicity. Monitoring sodium level is important in clients receiving lithium, not phenytoin. Hemoglobin level and white blood cell count are not directly related to phenytoin therapy monitoring.

Correct Answer: D

Rationale: The abdomen is a common site for subcutaneous injections due to its accessibility and ample subcutaneous tissue. Subcutaneous injections are typically given in areas with a layer of fat between the skin and muscle, such as the abdomen, to allow for slow and consistent absorption of the medication. The deltoid muscle is more appropriate for intramuscular injections, not subcutaneous. The dorsogluteal muscle and ventrogluteal muscle are also more suited for intramuscular injections, not subcutaneous.

Correct Answer: C

Rationale: The correct answer is C: Liver. The liver is located in the right upper hypochondriac region of the abdomen. The duodenum (Choice A) is located in the right upper quadrant but not directly underneath the right upper hypochondriac region. The gastric pylorus (Choice B) is part of the stomach and is located more centrally in the abdomen. The spleen (Choice D) is located in the left upper quadrant of the abdomen, not underneath the right upper hypochondriac region.

Correct Answer: C

Rationale: The correct answer is C: Osmosis. Osmosis is the homeostatic cellular transport mechanism that moves water from a hypotonic to a hypertonic fluid space to maintain cellular balance. In osmosis, water moves across a semi-permeable membrane from an area of low solute concentration (hypotonic) to an area of high solute concentration (hypertonic). This process helps regulate the water content inside cells. Choices A, B, and D are incorrect. Filtration involves the movement of solutes and solvents through a membrane due to a pressure difference, diffusion is the movement of solutes from an area of high concentration to low concentration, and active transport requires energy to move substances against their concentration gradient.
