1. How is the equalization of solute concentration of intracellular fluids (ICFs) and extracellular fluids (ECFs accomplished?

• A. Semipermeable membranes.
• B. Hydration.
• C. Osmotic pressure.
• D. Perspiration.

Correct answer: C

Rationale: The correct answer is C, osmotic pressure. Osmotic pressure within the body equalizes the solute concentration of ICFs and ECFs by shifting small amounts of water in the direction of higher concentration solute. Semipermeable membranes separate one fluid compartment from another and do not directly equalize solute concentrations. Hydration and perspiration are important elements of fluid balance but do not directly achieve the equalization of solute concentrations between ICFs and ECFs, which is primarily regulated by osmotic pressure.

2. Which lipid contains 3 fatty acids?

• A. cholesterol
• B. phospholipid
• C. saturated
• D. triglyceride

Correct answer: D

Rationale: The correct answer is 'D. triglyceride.' Triglycerides are composed of one glycerol molecule and three fatty acids, making them the primary form of stored fat in the body. Cholesterol (A) is a different type of lipid, phospholipids (B) have two fatty acids, and 'saturated' (C) refers to the structure of fatty acids, not a specific lipid containing 3 fatty acids.

3. Which type of medication is most likely to induce xerostomia?

• A. Antibiotics
• B. Diuretics
• C. Local anesthetics
• D. Anticholinergics

Correct answer: D

Rationale: The correct answer is D, Anticholinergics. Anticholinergic medications commonly cause xerostomia by inhibiting saliva production, leading to dry mouth. Antibiotics (choice A) are not typically associated with xerostomia. Diuretics (choice B) increase urine production but do not directly affect saliva production. Local anesthetics (choice C) are used to numb specific areas during dental procedures and do not induce xerostomia.

4. Loss of smell results in a condition that limits the capacity to detect the flavor of food and beverages, called:

• A. hypergeusia
• B. dysgeusia
• C. anosmia
• D. phantom taste

Correct answer: C

Rationale: The correct answer is C: anosmia. Anosmia refers to the loss of smell, which significantly affects the ability to detect flavors. Hypergeusia and dysgeusia, choices A and B, refer to heightened or distorted taste, respectively. 'Phantom taste' in choice D is not the correct term for the condition described in the question.

5. While the client has a pulse oximeter on his fingertip, you notice that sunlight is shining on the area where the oximeter is. Your action will be to:

• A. Set and turn on the alarm of the oximeter
• B. Do nothing since there is no identified problem
• C. Cover the fingertip sensor with a towel or bedsheet
• D. Change the location of the sensor every four hours

Correct answer: B

Rationale: In this scenario, the correct action is to do nothing since there is no identified problem with the sunlight shining on the area where the oximeter is placed. The functionality of the oximeter is not affected by sunlight, so covering it or changing its location unnecessarily could disrupt the monitoring process. Setting the alarm or changing the sensor location every four hours is not indicated in this situation and may lead to unnecessary interventions. It's essential to assess the situation carefully and intervene only when necessary, ensuring that care provided is appropriate and effective.
