A nurse in an emergency department is caring for a patient with a deep laceration on his left lower forearm. After observing standard precautions, which of the following actions should the nurse take?
Apply a tourniquet just below the elbow.
Elevate the limb and apply ice.
Clean the wound.
Apply pressure above the wound.
The Correct Answer is B
Choice A reason: Applying a tourniquet just below the elbow is not recommended as the first line of action for a deep laceration unless there is life-threatening hemorrhaging that cannot be controlled by direct pressure. Tourniquets are used as a last resort because they can cause tissue damage.
Choice B reason: Elevating the limb and applying ice can help reduce bleeding and swelling. Elevation uses gravity to help reduce blood flow to the injury, and the cold from the ice constricts blood vessels, further helping to control bleeding and reduce swelling.
Choice C reason: Cleaning the wound is important, but it should not be the first action taken. The initial focus should be on stopping the bleeding. Once bleeding is controlled, the wound can be cleaned to prevent infection.
Choice D reason: Applying pressure directly to the wound with a clean cloth or bandage is the first step in controlling bleeding. However, the question specifies applying pressure above the wound, which would not be effective in controlling bleeding from the wound itself.

Correct Answer is A
Explanation
Choice A reason: Urine specific gravity measures the kidney's ability to concentrate urine. A normal range is typically 1.005–1.030. A value of 1.020 indicates adequate hydration and suggests that the patient is responding well to IV fluid therapy.
Choice B reason: Serum sodium levels reflect electrolyte balance. The normal range is 135–145 mEq/L. A level of 165 mEq/L is significantly elevated, indicating hypernatremia, which could be a sign of inadequate hydration and not a positive response to treatment.
Choice C reason: Hematocrit represents the proportion of blood volume occupied by red blood cells. Normal ranges are 38.3–48.6% for men and 35.5–44.9% for women. A hematocrit of 48% is at the upper limit of normal and does not specifically indicate the effectiveness of dehydration treatment.
Choice D reason: Blood urea nitrogen (BUN) levels can indicate renal function and hydration status. The normal range is 7–20 mg/dL. A BUN of 12 mg/dL is within the normal range and does not specifically reflect the patient's response to IV fluids for dehydration.
Correct Answer is C
Explanation
Choice A: Sleepy, but arousing when the name is called
Feeling sleepy after receiving morphine is a common side effect. However, the fact that the client can be aroused when their name is called suggests that this is not necessarily an adverse effect.
The nurse should continue monitoring the client but may not consider this as a significant adverse reaction.
Choice B: Pain level of 6 on a scale from 0 to 10
Pain relief is one of the intended effects of morphine. Therefore, experiencing pain reduction is not an adverse effect.
The nurse would likely view this as a positive response to the medication.
Choice C: Respiratory rate of 8/min
A respiratory rate of 8 breaths per minute is significantly low and indicates respiratory depression, which is a serious adverse effect of morphine.
The nurse should be concerned about this finding and take appropriate action.
Choice D: SaO2 94%
An oxygen saturation (SaO2) level of 94% is within the normal range (usually 95% or higher). It is unlikely to be directly related to morphine administration.
While this value is not concerning, the nurse should continue monitoring the client's oxygen saturation.
