A nurse is assessing a client who sustained a basal skull fracture and notes a thin stream of clear drainage coming from the client's right nostril. Which of the following actions should the nurse take first?
Test the drainage for the halo sign.
Ask the client to blow his nose.
Notify the physician.
Suction the nostril.
The Correct Answer is A
Choice A reason:Testing the drainage for the halo sign is the first action the nurse should take, as clear drainage from the nose following a basal skull fracture could indicate a cerebrospinal fluid (CSF) leak, which contains glucose.
Choice B reason:Asking the client to blow his nose could potentially increase the risk of infection or worsen a CSF leak and is not recommended as a first action.
Choice C reason:While notifying the physician is important, it should be done after confirming whether the drainage is CSF, which would require immediate medical intervention.
Choice D reason:Suctioning the nostril is not the first action to take, as it could potentially disrupt the site of the leak and is not diagnostic of a CSF leak.

Correct Answer is ["60"]
Explanation
- Step 1: Identify the required dose in grams. The client is scheduled to receive 30 grams of lactulose.
- Step 2: Identify the concentration of the available solution. The available solution contains 5 grams of lactulose per 10 mL.
- Step 3: Calculate the volume of solution needed to deliver the required dose. We can set up a proportion to solve for this:
- 5 grams is to 10 mL as 30 grams is to X mL.
- In other words, 5 g : 10 mL = 30 g : X mL.
- Step 4: Solve for X using cross-multiplication and division:
- Cross-multiplication gives us: 5 g × X mL = 30 g × 10 mL.
- Simplifying this gives us: 5X = 300.
- Dividing both sides by 5 gives us: X = 300 ÷ 5.
- Calculating the division gives us: X = 60.
60 mL of the lactulose solution should be poured into the medication cup to administer the required dose of 30 grams.
Correct Answer is D
Explanation
Choice A reason: Anorexia, or loss of appetite, is not typically a direct manifestation of left-sided heart failure. While it can be associated with many medical conditions and may occur in the context of heart failure due to overall decreased well-being, it is not a specific indicator of left-sided heart failure.
Choice B reason: Weight gain can be associated with heart failure, but it is more commonly a sign of right-sided heart failure, where fluid accumulates in the body tissues, causing swelling and weight increase. In left-sided heart failure, weight gain is not as prominent because the primary issue is the backup of blood into the lungs, not fluid retention in the tissues.
Choice C reason: A distended abdomen can occur in heart failure due to fluid accumulation; however, it is more characteristic of right-sided heart failure, where the failure of the right ventricle leads to systemic congestion, including the abdominal area. In left-sided heart failure, the primary effect is on the lungs, not the abdomen.
Choice D reason: Dyspnea, or difficulty breathing, is a hallmark symptom of left-sided heart failure. It occurs due to the backup of blood in the pulmonary circulation, which leads to pulmonary congestion and reduced oxygen exchange. Patients may experience shortness of breath, especially during exertion or when lying flat (orthopnea), and may wake up at night with shortness of breath (paroxysmal nocturnal dyspnea).
Left-sided heart failure, often caused by conditions like valvular heart disease, leads to a decrease in the heart’s ability to pump blood effectively. This results in a buildup of pressure in the lungs, manifesting as dyspnea, which is an important symptom for nurses and other healthcare providers to recognize and manage promptly.
