• Question
Increased tendency of the tissues to hold water in the extra-cellular space is called as
1.Cutaneous edema 2.Lymphedema 3.Myxedema 4.Peripheral edema 5.Pitting edema
Correct Answer: Correct Answer: C. Myxedema
Explanation: In myxedema, edema occurs because of an increased tendency of the
tissues to hold water in the extra-cellular space; there is also an increase in hydrophilic
carbohydrate-rich molecules embedded in the tissue matrix. All other above-mentioned
edemas are not related toincreased tendency of the tissues to hold water in the
extra-cellular space.
• Question
A nurse cares for an elderly patient with hypertensive crisis. Which pharmaceutical
intervention is considered as the most fast acting one in the treatment of hypertensive
crisis? 1.Sodiumnitroprusside 2.Clonidine 3.Captopril 4.Amlodipine 5.Indapamide
Correct Answer: Correct Answer: A. Sodiumnitroprusside
Explanation: Immediate treatment for hypertensive crisis is with intravenous sodium
nitroprusside. This drug is considered as a fast acting drug. The other above-mentioned
drugs are anti-hypertensives. If sodium nitroprusside is unavailable some other drugs
are also used, but it will take several minutes for the other drugs to have onset of action.
After initial treatment, with sodium nitroprusside the blood pressure is reduced to
normal, slowly.
• Question
A nurse cares for a 55-year-old male patient with severe respiratory failure. The patient
is managed with endotracheal intubation and mechanical ventilation. Which of the
following parameters would the patient possibly have? 1.PaO2 less than 50 mmHg
2.PaO2 less than 80 mmHg 3.PaO2 less than 70 mmHg 4.PaO2 less than 60 mmHg
5.PaO2 less than 90 mmHg
Correct Answer: Correct Answer: A. PaO2 less than 50 mmHg
Explanation: When thePaO2 is less than 50 mmHg, endotracheal intubation and
mechanical ventilation is used in case of respiratory failure, then the situation is
considered as a severe condition. The other above-mentioned oxygen concentrations
are usually managed with oxygen administration. Drugs like respiratory stimulants are
used in case of overdose of sedative drugs.
, • Question
A patient who was on anti-psychotics for a period of 10 years developed cogwheel
rigidity, bradykinesia, tremors, and postural instability. What would a hospice nurse infer
from the symptoms? 1.The patient is likely to have pseudoparkinsonism. 2.The patient is
likely to have psychosis. 3.The patient is likely to have tardive dyskinesia. 4.The patient
is likely to have acute dystonic reactions. 5.The patient is likely to have encephalitis.
Correct Answer: Correct Answer: A. The patient is likely to have pseudoparkinsonism
Explanation: Drug-induced parkinsonism includes the symptoms of cogwheel rigidity,
bradykinesia, tremors, and postural instability. It is also known as pseudoparkinsonism.
The above-featured symptoms in the patient are typically seen in pseudoparkinsonism.
The other above-mentioned options are present in extrapyramidal symptoms along with
pseudoparkinsonism.
• Question
The triage nurse is working in an emergency department. Which patient must be
assessed first? 1.Massive uncontrolled bleeding 2.Multiple fractures 3.Renal calculi
4.Chronic headache 5.Acute psychosis
Correct Answer: Correct Answer: A. Massive uncontrolled bleeding
Explanation: Massive uncontrolled bleeding is life threatening and it is given the first
priority and continuous assessment in triage nursing. Multiple fractures, renal calculi
and acute psychosis are the second priority as the condition is considered as urgent in
triage nursing. It needs assessment once in half an hour. Chronic headache is
considered non-urgent; it needs assessment once in every 2 hours.
• Question
A nurse educates a patient with Vincent's angina that the treatment of the condition will
include all of the following except 1.Chlorhexidine mouth rinses, twice daily
2.Application of topical antibiotics 3.Consumption of high-protein diet 4.Frequent need
for debridement 5.Consumption of high-fiber diet
Correct Answer: Correct Answer: E. Consumption of high-fiber diet
Explanation: A patient with Vincent's angina needs chlorhexidine mouth washes two
times a day. Since Vincent's angina is a bacterial infection, treatment also includes
application of topical antibiotics and frequent debridement. The patient must take soft
nutritious diet, which must be rich in protein. The patient must avoid high-fiber diet.
