A nurse is reviewing the laboratory results for four clients. Which of the following results is the priority for the nurse to report to the provider?
A. WBC 11,000/mm² in a client who is starting treatment for a methicillin-resistant staphylococcus aureus (MRSA) infection.
An elevated WBC count (11,000/mm²) in a client starting treatment for MRSA infection may indicate an inflammatory response, but it is expected in this scenario, and the priority is not as high as other critical lab values.
B. Serum pH 7.25 in a client who has type 1 diabetes mellitus.
A serum pH of 7.25 indicates acidosis, which is a potentially life-threatening condition. In type 1 diabetes mellitus, diabetic ketoacidosis (DKA) is a common complication that can lead to metabolic acidosis. This lab result is a priority as it requires immediate attention.
C. Hematocrit 26% in a client who has sickle cell disease.
Hematocrit of 26% in a client with sickle cell disease might be low, but it is not the priority over the critically abnormal lab value of serum pH in option B.
D. Urine specific gravity 1.032 in a client who is diagnosed with dehydration.
A urine specific gravity of 1.032 in a client diagnosed with dehydration is elevated, indicating concentrated urine due to dehydration. While dehydration is concerning, it is not as high-priority as the potentially life-threatening acidosis in option B.

A nurse is caring for a client who has chronic kidney disease. The nurse should expect the client to have which of the following clinical manifestations?
A. Fruity smelling breath.
Fruity-smelling breath is associated with diabetic ketoacidosis (DKA), which is not the expected manifestation of chronic kidney disease (CKD). DKA occurs in uncontrolled diabetes and is not the priority for this client.
B. Painful urination.
Painful urination is not a typical clinical manifestation of chronic kidney disease. It is more commonly associated with urinary tract infections or other urological issues.
C. Hypotension.
Hypotension may occur in end-stage kidney disease, but it is not specific to chronic kidney disease and is not a priority in this scenario.
D. Lethargy.
Lethargy is a common clinical manifestation of chronic kidney disease due to the accumulation of waste products in the blood, leading to uremia. It is a priority as it indicates the progression of the disease and the need for close monitoring and intervention.

A nurse is providing teaching to a client who has a new prescription for cephalexin oral suspension. Which of the following statements by the client indicates an understanding of the teaching?
A. "I will increase my consumption of foods high in potassium.".
Increasing potassium consumption is unrelated to cephalexin, an antibiotic. It is not a necessary precaution or action to take while on this medication.
B. "I will apply lotion to my skin if I feel any itching.".
Applying lotion to the skin to relieve itching is not related to cephalexin use. Itching is not a common side effect of this antibiotic, so the client's statement indicates a misunderstanding of the teaching.
C. "I will avoid sun exposure while taking this medication.".
Avoiding sun exposure is essential while taking cephalexin because it is known to cause photosensitivity reactions. Sun exposure can lead to severe skin reactions, so the client's statement indicates an understanding of the teaching.
D. "I will keep the medication refrigerated.".
Keeping the medication refrigerated is not necessary for cephalexin oral suspension. It should be stored at room temperature unless specified otherwise by the manufacturer. The client's statement suggests a misunderstanding of the medication storage instructions.

A nurse in an emergency department is assessing a client who has a basilar skull fracture and serosanguineous nasal discharge following a motor vehicle crash. Which of the following findings should the nurse identify as reliable for determining that the discharge is cerebrospinal fluid?
A. Papilledema.
Papilledema refers to swelling of the optic disc in the eye, which can occur due to increased intracranial pressure. While it may be present in cases of basilar skull fracture, it is not a reliable finding for determining the discharge of cerebrospinal fluid (CSF).
B. Halo sign.
The halo sign is a reliable finding for determining that the nasal discharge is cerebrospinal fluid. The halo sign is characterized by a ring of blood surrounded by a clear or yellowish fluid (CSF) on a dressing or tissue. This occurs because blood from the fracture mixes with the clear CSF, creating a distinct appearance.
C. Racoon's eyes.
Racoon's eyes, also known as periorbital ecchymosis, is a term used to describe bruising around the eyes. While it can be seen in basilar skull fractures, it is not specific to cerebrospinal fluid leakage and, therefore, not reliable for identifying the nasal discharge as CSF.
D. Elevated WBCs.
Elevated white blood cells (WBCs) in the nasal discharge can indicate infection, inflammation, or an immune response. However, it does not provide direct evidence that the discharge is cerebrospinal fluid, so this is not a reliable finding for determining the nature of the nasal discharge in this context.
