1. When considering the structural organization of the human body, what is the basic unit of life?

Correct answer: D

Rationale: The basic unit of life is the cell. Cells are considered the fundamental unit of life because they are capable of carrying out all the processes necessary for life, such as growth, reproduction, responding to stimuli, and more. While chemicals, atoms, and molecules are essential components of cells and living organisms, they are not considered the basic unit of life. Chemicals are general substances, atoms are the smallest units of matter, and molecules are combinations of atoms. Therefore, the correct answer is cells, as they are the building blocks of all living organisms.

2. Which of the following situations indicates the need to file an incident report?

Correct answer: D

Rationale: An incident report is necessary for documenting unexpected events that occur in a healthcare setting. Situations that warrant filing an incident report include client accidents, medication errors, security problems, or disruptive behaviors that involve clients, families, or visitors. In this scenario, when a client's spouse displays disruptive behavior and is asked to leave the premises, it is essential to document this incident to ensure a record of the event and its resolution. Choices A, B, and C do not involve disruptive behavior or safety concerns that would require an incident report to be filed.

3. What is the MOST ACCURATE statement regarding the ESR test?

Correct answer: C

Rationale: The erythrocyte sedimentation rate (ESR) is a non-specific screening test for inflammation in the body. It is not used as a definitive diagnostic tool for specific conditions. When ESR results are abnormal, they indicate the presence of inflammation, which can be caused by various reasons. Therefore, abnormal results should be followed by additional testing to determine the underlying cause. The ESR test measures the rate at which red blood cells settle in a vertical tube over the span of one hour, and results are reported in millimeters per hour. Choice A is incorrect because ESR results are not solely diagnostic for any specific condition. Choice B is incorrect as abnormal ESR results do not directly indicate a potentially fatal illness without further investigation. Choice D is incorrect as the results are reported in millimeters per hour, not per minute.

4. Which of the following is an example of client handling equipment?

Correct answer: B

Rationale: Client handling equipment is designed to reduce stress and workload on healthcare professionals who assist, turn, or lift clients, aiming to decrease the risk of injuries from improper lifting techniques. A height-adjustable bed is a prime example of client handling equipment as it allows healthcare providers to raise the client to a suitable working height, facilitating care provision. Choices A, C, and D are not examples of client handling equipment. While a wheelchair, shower chair, and call light are essential in client care settings, they are not intended to aid in handling and lifting clients.

5. Which of the following signs or symptoms indicates a possible nutritional deficiency?

Correct answer: D

Rationale: A client with poor nutritional intake may have pale mucous membranes surrounding the eye, or the conjunctiva. This area should normally be pink, indicating good circulation and a lack of irritation or dryness. Improper nutrition can manifest as numerous signs in the body, including bowed legs, pale mucous membranes, a smooth or beefy tongue, and poor muscle tone. Subcutaneous fat at the waist and abdomen is not a sign of nutritional deficiency but rather of excess fat deposition. The presence of papillae on the surface of the tongue is normal and not indicative of a nutritional deficiency. Straight arms and legs are also typical anatomical features and not specifically related to nutritional deficiencies.
