1. Patients exhibiting signs of cyanosis will:

• A. show signs of hyperoxia.
• B. have increased O2 saturation.
• C. have blood levels of CO2 higher than O2 levels.
• D. None of the above.

Correct answer: C

Rationale: Cyanosis is a bluish discoloration of the skin and mucous membranes resulting from low blood oxygen levels. When a patient exhibits cyanosis, it indicates that their blood is poorly oxygenated, leading to a higher concentration of CO2 compared to oxygen. Options A and B are incorrect as cyanosis is associated with low oxygen levels, not hyperoxia or increased O2 saturation. Therefore, the correct answer is that patients exhibiting cyanosis will have blood levels of CO2 higher than O2 levels.

2. When performing CPR, at what rate should chest compressions be applied?

• A. 100 per minute
• B. 60 per minute
• C. As quickly as possible
• D. 200 per minute

Correct answer: A

Rationale: During CPR, chest compressions should be applied at a rate of 100 compressions per minute in order to effectively circulate blood and oxygen to vital organs. Option A, '100 per minute,' is the correct answer as it aligns with the recommended compression rate in CPR guidelines. Option B, '60 per minute,' is incorrect as it is too slow and may not provide adequate circulation. Option C, 'As quickly as possible,' is vague and does not specify the recommended compression rate. Option D, '200 per minute,' is incorrect as it exceeds the recommended rate and may not be as effective in maintaining perfusion.

3. A client with an enlarged prostate is having trouble starting his flow of urine when using the bathroom. Another name for this condition is:

• A. Hesitancy
• B. Oliguria
• C. Retention
• D. Urgency

Correct answer: A

Rationale: Urinary hesitancy occurs when a client has difficulty starting a flow of urine while using the bathroom. Hesitancy may be due to physiological factors, such as obstruction from an enlarged prostate, or due to psychological factors, such as anxiety or embarrassment. Oliguria refers to decreased urine output, retention is the inability to empty the bladder fully, and urgency is the sudden and strong need to urinate.

4. Which of the following descriptions best describes the function of the thyroid gland?

• A. The thyroid gland converts glucose into glycogen
• B. The thyroid gland secretes cortisol during times of stress
• C. The thyroid gland regulates body metabolism
• D. The thyroid gland affects skin pigmentation

Correct answer: C

Rationale: The thyroid gland is responsible for secreting thyroxine (T4) and triiodothyronine (T3), which work to regulate the metabolism of the body's cells. The primary function of the thyroid gland is to control the body's metabolic rate, affecting processes such as heart rate, temperature regulation, and energy levels. Choices A, B, and D are incorrect because the thyroid gland is not involved in converting glucose into glycogen, secreting cortisol, or affecting skin pigmentation. Instead, the primary role of the thyroid gland is to regulate the metabolism and energy balance in the body.

5. Which of the following bony landmarks is described as a large, blunt, irregularly shaped process found on the lateral aspect of the proximal femur?

• A. Tubercle
• B. Tuberosity
• C. Condyle
• D. Trochanter

Correct answer: D

Rationale: The correct answer is D: Trochanter. The Greater Trochanter is located on the lateral aspect of the proximal femur and is a large, blunt, irregularly shaped bony process. It serves as an important attachment site for many muscles of the legs, providing leverage and movement. Choice A, Tubercle, is a small rounded projection, usually for the attachment of a ligament or tendon. Choice B, Tuberosity, is a large rounded projection, also typically for muscle attachment. Choice C, Condyle, refers to a rounded articular surface at the end of a bone, usually involved in joints.
