ISPN考试模拟试题(二十五)

Questions

1. A nurse is caring for a client with albuminuria resulting in edema. What pressure change does the nurse determine as the cause of the edema?

A. Decrease in tissue hydrostatic pressure

B. Increase in plasma hydrostatic pressure

C. Increase in tissue colloid osmotic pressure

D. Decrease in plasma colloid oncotic pressure


2. A nurse is reviewing the health care provider’s orders for a client who was admitted with dehydration as a result of prolonged watery diarrhea. Which order should the nurse question?

A. Oral psyllium (Metamucil)

B. Oral potassium supplement

C. Parenteral half normal saline

D. Parenteral albumin (Albuminar)


3. A nurse is analyzing how a hyperglycemic client’s blood glucose can be lowered. The nurse considers that the chemical that buffers the client’s excessive acetoacetic acid is:

A. potassium.

B. bicarbonate.

C. carbon dioxide.

D. sodium chloride.


4. For what clinical indicator should a nurse assess a client who is having a gastric lavage?

A. Decreased serum pH

B. Increased serum oxygen level

C. Increased serum bicarbonate level

D. Decreased serum osmotic pressure


5. A client is in a state of uncompensated acidosis. What approximate arterial blood pH does the nurse expect the client to have?

A. 7.20

B. 7.35

C. 7.45

D. 7.48 

Rationales

1.D 

Because the plasma colloidal oncotic pressure (COP) is the major force drawing fluid from the interstitial spaces back into the capillaries, a drop in COP caused by albuminuria results in edema.

A,Hydrostatic tissue pressure is unaffected by alteration of protein levels; colloidal pressure is affected.

B, Hydrostatic pressure is influenced by the volume of fluid and the diameter of the blood vessel, not directly by the presence of albumin.

C,The osmotic pressure of tissues is unchanged.

Client Need: Physiological Adaptation;

Cognitive Level: Application;

Nursing Process: Assessment/Analysis;

Reference: Ch 3, Acid-Base Balance


2.D 

Albumin is hypertonic and will draw additional fluid from the tissues into the intravascular space.

A,This will absorb the watery diarrhea, giving more bulk to the stool.

B,This is appropriate because diarrhea causes potassium loss.

C,This is a hypotonic solution, which can correct dehydration.

Client Need:Pharmacological and Parenteral Therapies;

Cognitive Level:Application;

Nursing Process: Evaluation/Outcomes;

Reference: Ch 3, Acid-Base Balance


3.B 

Sodium bicarbonate is a base and one of the major buffers in the body.

A,Potassium, a cation, is not a buffer; only a base can buffer an acid.

C,Carbon dioxide is carried in aqueous solution as carbonic acid (H2CO3 ); an acid does not buffer another acid.

D,Sodium chloride is not a buffer; it is a salt.

Client Need: Physiological Adaptation;

Cognitive Level: Comprehension;

Nursing Process: Assessment/Analysis;

Reference: Ch 3, Acid-Base Balance


4.C 

Gastric lavage causes an excessive loss of gastric fluid, resulting in excessive loss of hydrochloric acid (HCL) that can lead to alkalosis; the HCL is not available to neutralize the sodium bicarbonate (NaHCO3 ) secreted into the duodenum by the pancreas. The intestinal tract absorbs the excess bicarbonate, and alkalosis results.

A,Gastric lavage will lead to alkalosis, which is associated with increased pH.

B,Gastric lavage will not affect oxygen levels. 

D,Gastric lavage may lead to dehydration, which will increase osmotic pressure.

Client Need:Reduction of Risk Potential;

Cognitive Level:Application;

Nursing Process:Evaluation/Outcomes;

Reference:Ch 3, Acid-Base Balance


5.A 

The pH of blood is maintained within the narrow range of 7.35 to 7.45. When there is an increase in hydrogen ions, the respiratory, buffer, and renal systems attempt to compensate to maintain the pH. If compensation is not successful, acidosis results and is reflected in a lower pH.

B, C,This is within the acceptable range for pH.

D,This is slightly alkaline.

Client Need:Physiological Adaptation;

Cognitive Level:Analysis;

Nursing Process:Assessment/Analysis;

Reference:Ch 3, Acid-Base Balance
