A client with multiple sclerosis (MS) is receiving interferon beta-1b 0.1875 mg subcutaneously every other day. The nurse reconstitutes the vial by slowly injecting 1.2 mL of diluent into the interferon vial for a reconstituted solution of 0.25 mg/1 mL. How many mL should the nurse administer?

(Enter numeric value only. If rounding is required, round to the nearest hundredth.)

Answer and Explanation

The Correct Answer is ["0.75"]

Calculate the volume of the reconstituted solution that contains the prescribed dose of 0.1875 mg. Since the reconstituted solution has a concentration of 0.25 mg per 1 mL, we can set up a proportion to find the answer: (0.1875 mg / X mL) = (0.25 mg / 1 mL).

Solving for X gives us X = (0.1875 mg * 1 mL) / 0.25 mg, which equals 0.75 mL.

Therefore, the nurse should administer 0.75 mL of the reconstituted solution.

Correct Answer is ["A","B","C"]

Explanation

Blood pressure 90/62 mm Hg

A blood pressure of 90/62 mm Hg indicates hypotension, which could be indicative of hypovolemia (low blood volume) due to postpartum hemorrhage. Hypotension needs immediate evaluation and intervention to prevent further complications.

Oxygen saturation of 89%

An oxygen saturation of 89% on room air is below the normal range (typically 95-100%). This suggests the client is not adequately oxygenating, which could be due to various reasons such as respiratory compromise or inadequate ventilation. Immediate follow-up is necessary to determine the cause and initiate appropriate interventions.

Fundus rotated to the right

The displacement of the fundus could be due to the presence of a distended bladder pushing the uterus to one side which may increase uterine atony.

A. Lung biopsy. B. Antibody testing. C. Sweat test. D. Spirometry.

Correct Answer is D

Explanation

Rationale

A. A. lung biopsy involves obtaining a tissue sample from the lung for microscopic examination. It is typically performed to diagnose conditions such as lung cancer or to investigate unusual findings seen on imaging studies. However, for a client with COPD experiencing increased shortness of breath, a lung biopsy is not typically indicated as a first-line investigation. It is more invasive and usually reserved for specific diagnostic purposes other than routine evaluation of COPD symptoms.

B. Antibody testing is used to detect antibodies specific to certain infections or autoimmune conditions. It is not typically used in the routine evaluation of COPD symptoms unless there is suspicion of a specific autoimmune or infectious cause contributing to exacerbations, which is less common in COPD compared to other conditions.

C. A. sweat test is used to diagnose cystic fibrosis (CF), a genetic disorder that affects the lungs and digestive system. It measures the amount of chloride in sweat, which is elevated in individuals with CF. Since COPD and CF are distinct conditions with different underlying causes and diagnostic criteria, a sweat test is not appropriate for evaluating COPD symptoms.

D. Spirometry is the most appropriate test to schedule for evaluating a client with COPD who reports increased shortness of breath with activity. Spirometry measures lung function by assessing how much and how quickly a person can move air into and out of their lungs. It provides valuable information about the severity of airflow limitation, which is characteristic of COPD.
