A male client weighing 175 pounds is to receive an intramuscular injection into his deltoid of two milliliters (2 mL) of a viscous fluid.
Which needle size should a nurse use?
1/2 inch, 25 gauge.
1 inch, 23 gauge.
1-1/2 inches, 21 gauge.
2 inches, 16 gauge.
The Correct Answer is B
This needle size is appropriate for an intramuscular injection into the deltoid of a 175-pound adult male with a viscous fluid.
The needle length should be long enough to reach the muscle through the subcutaneous tissue, and the needle gauge should be suitable for the viscosity of the fluid. A 23-gauge needle is a common choice for intramuscular injections.
Choice A is wrong because a 1/2 inch needle is too short to reach the deltoid muscle in an adult male.
Choice C is wrong because a 1-1/2 inch needle is too long and may cause injury to the underlying nerves or blood vessels.
Choice D is wrong because a 16-gauge needle is too large and may cause excessive tissue trauma and pain.

Explanation
These are some of the common symptoms of hypothyroidism, which is a condition where the thyroid gland does not produce enough thyroid hormones. Thyroid hormones regulate the body’s metabolism, temperature and heart rate.
Choice A is wrong because a pulse of 126 is too high for hypothyroidism. Hypothyroidism usually causes a slow heart rate (bradycardia), not a fast one (tachycardia). A normal resting pulse rate for adults is between 60 and 100 beats per minute.
Choice E is wrong because a pulse of 54 is within the normal range for
hypothyroidism. Hypothyroidism can cause a pulse rate lower than 60 beats per minute, but this is not always abnormal. Some people, such as athletes, may have a lower resting pulse rate due to their fitness level.
The normal ranges for thyroid function tests are:
- Thyroid-stimulating hormone (TSH): 0.4 to 4.0 milli-international units per liter (mIU/L).
- Free thyroxine (T4): 0.8 to 2.8 nanograms per deciliter (ng/dL).
- Total triiodothyronine (T3): 80 to 220 ng/dL.
Correct Answer is A
Explanation
Using an automatic BP cuff with a shivering client with a history of an irregular heart rate can result in inaccurate and low readings.
This is because shivering can interfere with the cuff inflation and deflation, and an irregular heart rate can affect the accuracy of the device.
The nurse should intervene and use a manual BP cuff with a stethoscope instead.
Choice B is wrong because pulling the client’s ear pinna backward, up and out to obtain a tympanic membrane temperature is the correct technique for adults and older children. This helps to straighten the ear canal and allow the light to reflect on the tympanic membrane, which shares the same vascular artery as the hypothalamus.
Choice C is wrong because counting the client’s radial pulse who is supine with the forearm straight alongside the body is an appropriate method.
The radial pulse can be easily palpated at the wrist, and the supine position and straight forearm do not affect the pulse rate.
Choice D is wrong because counting the respirations for one full minute for a client with tachypnea is a recommended practice.
Tachypnea means rapid breathing, and counting for one full minute can ensure accuracy and detect any variations in the respiratory pattern.
