What are the major electrolytes in the extracellular fluid?
- A. potassium and chloride
- B. potassium and phosphate
- C. sodium and chloride
- D. sodium and phosphate
Correct Answer: C
Rationale: The correct answer is sodium and chloride. These two electrolytes are the major components of extracellular fluid. Potassium and phosphate (Choice B) are not the major electrolytes in the extracellular fluid. Potassium is primarily an intracellular ion, and phosphate is more abundant in the intracellular fluid and bones. Sodium and phosphate (Choice D) are also not the major electrolytes in the extracellular fluid. Chloride plays a crucial role in maintaining electrolyte balance and is predominantly found in extracellular fluid alongside sodium.

While undergoing hemodialysis, the client becomes restless and tells the nurse he has a headache and feels nauseous. Which of the following complications does the nurse suspect?
- A. Infection.
- B. Disequilibrium syndrome.
- C. Air embolus.
- D. Infection.
Correct Answer: C
Rationale: In this scenario, the client undergoing hemodialysis is experiencing symptoms like restlessness, a headache, and nausea. These symptoms are indicative of an air embolus, a serious complication that can occur during hemodialysis. Air embolus happens when air enters the bloodstream and can lead to symptoms like restlessness, a headache, and nausea. It is crucial for the nurse to suspect and address this complication promptly to prevent further harm to the client. Choices A and D (Infection) are less likely in this case, as the symptoms presented are more suggestive of an air embolus rather than an infection. Choice B (Disequilibrium syndrome) is also less likely as the symptoms described are not typical of this syndrome. Therefore, the correct answer is C: Air embolus.
In alcoholics with anemia:
- A. Pernicious anemia is more common than folic acid deficiency.
- B. Iron deficiency and folic acid deficiency can coexist.
- C. The alcohol interferes with iron absorption.
- D. Oral vitamin replacement is contraindicated.
Correct Answer: B
Rationale: In alcoholics with anemia, iron deficiency and folic acid deficiency can coexist due to poor dietary intake and malabsorption issues associated with chronic alcohol consumption. Pernicious anemia, primarily related to vitamin B12 deficiency, is not commonly seen in alcoholics. While alcohol can interfere with iron absorption, it is not the sole factor contributing to anemia in alcoholics. Oral vitamin replacement is not contraindicated in alcoholics with anemia; however, it may be less effective due to absorption issues related to alcohol consumption.
The client with peripheral vascular disease is reviewing self-care measures. Which of the following statements indicates proper self-care measures?
- A. "I like to soak my feet in the hot tub every day."?
- B. "I walk to the mailbox in my bare feet."?
- C. "I stopped smoking and only use chewing tobacco."?
- D. "I have my wife examine the soles of my feet each day."?
Correct Answer: D
Rationale: The correct answer is, "I have my wife examine the soles of my feet each day."? Clients with peripheral vascular disease should examine their feet daily for any signs of redness, dryness, or cuts. If the client is unable to do this themselves due to decreased sensation in their feet, a caregiver or family member should assist. Soaking feet in a hot tub should be avoided as the client may not be able to sense if the water is too hot, potentially causing burns. Walking barefoot can lead to injuries, so wearing shoes or slippers is recommended to minimize trauma. While quitting smoking is a positive step, using chewing tobacco can still constrict blood vessels, adversely affecting circulation in the extremities.
The client diagnosed with end-stage liver disease has completed an advance directive and a do-not-resuscitate (DNR) document and wishes to receive palliative care. Which of the following would correspond to the client's wish for comfort care?
- A. Positioning frequently to prevent skin breakdown and providing pain management and other comfort measures
- B. Carrying out vigorous resuscitation efforts if the client were to stop breathing, but no resuscitation if the heart stops beating
- C. Providing intravenous fluids when the client becomes dehydrated
- D. Providing total parenteral nutrition (TPN) if the client is not able to eat
Correct Answer: A
Rationale: Palliative care includes measures to prevent skin breakdown, pain management, and management of other symptoms that cause discomfort, as well as encouraging contact with family and friends. A DNR request precludes all resuscitative efforts related to respiratory or cardiac arrest, making choice B incorrect. Dehydration is a natural part of the dying process, so providing intravenous fluids as in choice C would not align with the client's wish for comfort care. Total parenteral nutrition (TPN) as in choice D is an invasive procedure meant to prolong life and is not part of palliative care, which focuses on improving quality of life rather than extending it.
The client is preparing to learn about the effects of isoniazid (INH). Which information is essential for the client to understand?
- A. Isoniazid should be taken with meals to reduce gastrointestinal upset.
- B. Prolonged use of isoniazid may result in dark, concentrated urine.
- C. Taking aluminum hydroxide (Maalox) with isoniazid can enhance the drug's effects.
- D. Consuming alcohol daily can increase the risk of drug-induced hepatitis.
Correct Answer: D
Rationale: It is crucial for the client to understand that consuming alcohol while on isoniazid can increase the risk of drug-induced hepatitis. Hepatic damage can lead to dark, concentrated urine. To minimize gastrointestinal upset, it is recommended to take isoniazid with meals rather than on an empty stomach. Additionally, the client should avoid taking aluminum-containing antacids like aluminum hydroxide with isoniazid, as it can reduce the drug's effectiveness. Choice A is incorrect because isoniazid should not be taken on an empty stomach to help reduce GI upset. Choice B is incorrect, as prolonged use of isoniazid does not typically cause dark, concentrated urine. Choice C is incorrect as taking aluminum hydroxide with isoniazid does not enhance the drug's effects; in fact, it may decrease its effectiveness.
