Which needle gauge should a nurse select when administering a medication subcutaneously?
8.
20.
21.
25.
The Correct Answer is D
The needle gauge size for subcutaneous injections should be between 25 and 31, depending on the patient’s size and the viscosity of the medication.
A smaller gauge number means a larger diameter needle, which can cause more pain and tissue damage.
Choice A is wrong because 8 is too large for subcutaneous injections and can cause bleeding and bruising.
Choice B is wrong because 20 is also too large for subcutaneous injections and can cause similar complications as choice A.
Choice C is wrong because 21 is still too large for subcutaneous injections and can cause discomfort and injury to the patient.
The needle length for subcutaneous injections should be between ½ inch and ⅝ inch, depending on the amount of subcutaneous tissue present. The nurse should pinch the skin and insert the needle at a 45-degree angle to ensure proper delivery of the medication.

Correct Answer is C
Explanation
This is because hepatitis C is a viral infection that spreads through contaminated blood and body fluids. IV drug use is one of the most common ways to get hepatitis C, especially if people share needles or other equipment.
Choice A is wrong because drinking contaminated water is not a risk factor for hepatitis
C. Hepatitis A and E are transmitted by the fecal-oral route, which can happen through contaminated water.
Choice B is wrong because eating raw chicken is not a risk factor for hepatitis C. Hepatitis E can be transmitted by eating undercooked meat from infected animals, but not chicken.
Choice D is wrong because unprotected intercourse is not a major risk factor for hepatitis
C. Hepatitis B and D are more likely to be transmitted by sexual contact than hepatitis
C. However, having multiple sexual partners or having sexually transmitted diseases can increase the risk of hepatitis
C. Normal ranges for hepatitis C tests depend on the type of test and the laboratory that performs it.
Some common tests are:
- Anti-HCV antibody test: This test detects antibodies to the hepatitis C virus in the blood.
A positive result means that the person has been exposed to the virus, but does not necessarily mean that they have an active infection. A negative result means that the person has never been exposed to the virus or has cleared it from their body.
- HCV RNA test: This test measures the amount of hepatitis C virus in the blood.
A positive result means that the person has an active infection and can transmit the virus to others. A negative result means that the person does not have an active infection or has cleared it from their body.
- HCV genotype test: This test identifies the strain or type of hepatitis C virus that the person has. There are six major genotypes of hepatitis C, numbered 1 to 6, and each one may respond differently to treatment.

A client with expiratory wheezing after an albuterol treatment.
This indicates that the client has a severe bronchospasm that is not responding to the medication and may lead to respiratory failure.
The client needs immediate intervention to improve airway patency and oxygenation.
Choice A is wrong because a fasting blood sugar of 187 mg/dL is high but not life- threatening. The normal range for fasting blood sugar is less than 99 mg/dL.
The client may have diabetes or prediabetes and needs further evaluation and treatment, but this is not a priority over choice B.
Choice C is wrong because a client who has been called to surgery 2 hours early may need some preparation and education, but this is not an urgent situation.
The client can wait until the nurse has assessed the other clients.
Choice D is wrong because a blood pressure of 178/90 mmHg is elevated but not critical. The normal range for blood pressure is less than 120/80 mmHg.
