A nurse is reviewing the laboratory results for a client who reports vomiting and diarrhea for 2 days.
Which of the following laboratory findings should the nurse expect?
Hypermagnesemia.
Hyponatremia.
Hypocalcemia.
D. Hyperkalemia.
The Correct Answer is B
This means low sodium levels in the blood.
Sodium is an electrolyte that helps regulate fluid balance and nerve and muscle function.
Vomiting and diarrhea can cause dehydration and loss of sodium through fluids.
Normal sodium levels are between 135 to 145 millimole/Liter.
Choice A is wrong because hypermagnesemia means high magnesium levels in the blood.
Magnesium is another electrolyte that helps with nerve and muscle function, as well as blood pressure and blood sugar regulation.
Hypermagnesemia is rare and usually caused by kidney failure or excessive use of magnesium supplements or laxatives.
Normal magnesium levels are between 1.46 to 2.68 milligram/deciliter.
Choice C is wrong because hypocalcemia means low calcium levels in the blood.
Calcium is an electrolyte that helps with bone health, muscle contraction, blood clotting and nerve signaling.
Hypocalcemia can be caused by vitamin D deficiency, kidney disease, thyroid problems or certain medications.
Normal calcium levels are between 8.8 to 10.7 milligram/deciliter.
Choice D is wrong because hyperkalemia means high potassium levels in the blood.
Potassium is an electrolyte that helps with nerve and muscle function, especially the heart.
Hyperkalemia can be caused by kidney disease, diabetes, adrenal gland disorders or certain medications.
Normal potassium levels are between 3.6 to 5.5 millimole/Liter.

Correct Answer is C
Explanation
The correct answer is choice C. The client who says “I need to learn how to perform a dressing change on my leg” is indicating an acceptance of the limb loss and a readiness to learn self-care skills.
This is a positive sign of coping and adaptation after an amputation surgery.
Choice A is wrong because the client who says “I am going to have to find someone who can take care of my leg at home” is expressing dependency and denial of the limb loss.
The client needs to be encouraged to participate in self-care activities and rehabilitation.
Choice B is wrong because the client who says “I stay awake at night because I keep thinking about my leg” is experiencing phantom limb sensation, which is a common phenomenon after amputation.
The client may benefit from pain management, distraction techniques, and counseling.
Choice D is wrong because the client who says “I know my family means well, but I don’t want visitors seeing my leg right now” is showing signs of social isolation and low self-esteem.
The client needs emotional support and reassurance from the nurse and family members.
Normal ranges for vital signs after amputation are blood pressure 120/80 mm Hg, pulse 60-100 beats/min, respiratory rate 12-20 breaths/min, and temperature 36.5-37.5°C.
Correct Answer is B
Explanation
This type of aphasia is caused by damage to the frontal lobe of the brain, which affects the ability to produce language.
People with expressive aphasia can understand speech and know what they want to say, but they have difficulty saying words or forming sentences.
They may speak in short phrases that require a lot of effort.
Choice A is wrong because receptive aphasia is a type of fluent aphasia that affects the ability to comprehend language.
People with receptive aphasia have difficulty understanding speech and may produce meaningless words or sentences.
Choice C is wrong because global aphasia is the most severe type of aphasia that affects both the production and comprehension of language.
People with global aphasia cannot speak many words and do not understand speech.
They also cannot read or write.
Choice D is wrong because sensory aphasia is not a common term for a type of aphasia.
It may refer to Wernicke’s aphasia, which is another type of fluent aphasia that affects the ability to produce meaningful language.
People with Wernicke’s aphasia can speak fluently but often use incorrect or invented words or phrases.
