1. The nurse is providing care for a patient with chronic obstructive pulmonary disease. When describing the process of respiration the nurse explains how oxygen and carbon dioxide are exchanged between the pulmonary capillaries and the alveoli. The nurse is describing what process?

A. Diffusion
B. Osmosis
C. Active transport
D. Filtration

Correct answer: A

Rationale:

2. Which of the following might the nurse assess in a patient diagnosed with hypermagnesemia?

A. Diminished deep tendon reflexes
B. Tachycardia
C. Cool clammy skin
D. Increased serum magnesium

Correct answer: A

Rationale: The correct answer is A: Diminished deep tendon reflexes. In a patient with hypermagnesemia, the nurse would assess for diminished deep tendon reflexes. Hypermagnesemia can lead to neuromuscular depression, causing a decrease in deep tendon reflexes. Tachycardia (choice B) is more commonly associated with hypomagnesemia. Cool clammy skin (choice C) is not typically a direct symptom of hypermagnesemia. While hypermagnesemia does involve increased serum magnesium levels (choice D), assessing serum levels is a laboratory test and not a clinical assessment like checking deep tendon reflexes.

3. 1.A nurse prepares to insert a peripheral venous catheter in an older adult client. Which action should the nurse take to protect the clients skin during this procedure?

A. Lower the extremity below the level of the heart.
B. Apply warm compresses to the extremity.
C. Tap the skin lightly and avoid slapping.
D. Place a washcloth between the skin and tourniquet

Correct answer: D

Rationale:

4. Which negative ion is most abundant in blood plasma?

A. Bicarbonate
B. Chloride
C. Hydroxide
D. Phosphate

Correct answer: B

Rationale: Chloride (Cl-) is the most abundant anion in blood plasma. It plays a crucial role in maintaining osmotic balance and acid-base homeostasis. Bicarbonate (Choice A) is important for buffering acids in the body but is not the most abundant negative ion in blood plasma. Hydroxide (Choice C) is not typically found in high concentrations in blood plasma. Phosphate (Choice D) is an important anion in the body but is not as abundant as chloride in blood plasma.

5. What is the main water-holding force in the blood capillaries?

A. Capillary blood pressure
B. Sodium in the blood plasma
C. Protein in the blood plasma
D. Chloride in the blood plasma

Correct answer: C

Rationale: The correct answer is C: Protein in the blood plasma. Plasma proteins, especially albumin, create oncotic pressure, which is the main force responsible for holding water within the blood capillaries. Capillary blood pressure (Choice A) is involved in pushing blood through the capillaries, while sodium and chloride in the blood plasma (Choices B and D) are electrolytes and do not play a significant role in the water-holding force within capillaries.
