A client has been treated for hypertension.
What blood pressure reading indicates to the nurse that the treatment is effective?
84/50 mmHg.
120/77 mmHg.
148/88 mmHg.
160/90 mmHg.
The Correct Answer is B
120/77 mmHg. This is because this blood pressure reading is within the normal range of less than 120/80 mmHg. Hypertension is defined as a blood pressure of 140/90 mmHg or higher.
Choice A is wrong because 84/50 mmHg is too low and may indicate hypotension, which can cause dizziness, fainting, or shock.
Choice C is wrong because 148/88 mmHg is above the normal range and indicates prehypertension, which is a risk factor for developing hypertension and cardiovascular disease.
Choice D is wrong because 160/90 mmHg is above the normal range and indicates stage 1 hypertension, which requires treatment with lifestyle changes and medication.

Correct Answer is B
Explanation
Heat application increases blood flow and reduces muscle spasms, which can help relieve pain and promote healing. However, heat should not be applied for longer than 30 minutes at a time, as it can cause tissue damage and inflammation.
Choice A is wrong because maximum benefits do not occur within the first five minutes.
It takes time for heat to penetrate the tissues and cause vasodilation.
Choice C is wrong because the heat should not be left in place for at least one hour to be effective.
This can lead to burns, increased edema, and decreased blood flow.
Choice D is wrong because heat can not be left in place for as long as 12 hours without harmful effects.
This can cause severe tissue damage, infection, and necrosis.
Normal ranges for heat application are between 104°F and 113°F (40°C and 45°C).
The temperature should be checked frequently and adjusted according to the patient’s comfort and tolerance.
The skin should also be inspected for signs of erythema, blisters, or burns.
Correct Answer is C
Explanation
This is because renal calculi can cause renal colic, which is a sudden and intense pain in the flank area that radiates to the groin or testicles.
The pain is caused by the stone obstructing the ureter and triggering spasms.
Choice A is wrong because a feeling of pressure in the bladder is more likely to indicate a lower urinary tract infection or an overactive bladder.
Choice B is wrong because a mild, burning pain when urinating is more likely to indicate a urinary tract infection or a urethral injury.
Choice D is wrong because a constant, dull, aching pain in the right upper quadrant is more likely to indicate a liver or gallbladder problem.
Normal ranges for urine pH are 4.5 to 8.0, and for specific gravity are 1.005 to 1.030.
