The nurse is teaching a client about the use of syringes and needles for home administration of medications. Which action by the client indicates an understanding of standard precautions?
Washes hands before handling the needle and syringe.
Wears gloves to dispose of the needle and syringe.
Dons a face mask before administering the medication.
Removes the needle before discarding used syringes.
The Correct Answer is A
Choice A reason: Hand hygiene is the foundation of Standard Precautions and the single most effective action to prevent transmission of infectious agents. Performing handwashing or using an alcohol‑based hand rub immediately before preparing or administering an injection removes transient microorganisms acquired from touching surfaces and protects both the client and the environment from contamination
Choice B reason: While wearing gloves during handling and disposal of contaminated sharps is recommended whenever there is potential contact with blood or body fluids, it is a secondary barrier. Reliance on gloves alone is insufficient because gloves can have micro‑perforations and are removed after use, making hand hygiene before and after glove use the priority
Choice C reason: Donning a face mask before administering the medication is not a necessary action to indicate an understanding of standard precautions. A face mask is only required when there is a risk of droplet transmission of infectious agents, such as when caring for a client with respiratory infections. It is not needed for self-administration of medications, unless the medication is aerosolized or nebulized.
Choice D reason: Removing the needle before discarding used syringes is not a safe action to indicate an understanding of standard precautions. It increases the risk of needle-stick injuries and contamination. The needle and syringe should be disposed of as a single unit in a puncture-resistant container.

Correct Answer is B
Explanation
Choice A reason: Serum potassium and sodium levels are not relevant to the assessment of the wound infection. They are electrolytes that regulate fluid balance, nerve conduction, and muscle contraction. They may be affected by dehydration, renal failure, or diuretics.
Choice B reason: Neutrophil count is the most relevant laboratory value to note before reporting the wound infection. Neutrophils are white blood cells that fight bacterial infections and inflammation. A high neutrophil count indicates an acute infection or inflammation, while a low neutrophil count indicates a compromised immune system or a chronic infection.
Choice C reason: Blood pH level is not relevant to the assessment of the wound infection. It is a measure of the acidity or alkalinity of the blood. It may be affected by respiratory or metabolic disorders, such as acidosis or alkalosis.
Choice D reason: Hematocrit is not relevant to the assessment of the wound infection. It is the percentage of red blood cells in the blood. It may be affected by anemia, dehydration, or polycythemia.
Correct Answer is C
Explanation
Choice A reason: Removing the nasal cannula is not appropriate as it would deprive the client of supplemental oxygen. The client's oxygen saturation is below the normal range of 95% to 100%, indicating hypoxemia.
Choice B reason:While increasing oxygen might seem appropriate, this should only be done after verifying the accuracy of the pulse oximeter reading and assessing the client’s overall condition. Automatically increasing oxygen without further assessment could delay addressing other underlying issues or lead to over-oxygenation in clients with certain conditions like COPD.
Choice C reason:The first step is to ensure the accuracy of the pulse oximeter reading by checking its placement and ruling out factors that can interfere with accurate readings, such as poor circulation, cold extremities, nail polish, or motion artifacts. This ensures that the subsequent intervention is based on reliable data.
Choice D reason: Switching to a non-rebreather mask is not necessary as it would deliver a high concentration of oxygen (up to 100%) that may be excessive for the client. A nasal cannula can deliver oxygen from 1 to 6 L/minute, depending on the client's needs.
