Nursing Elites

1. A client with a history of atrial fibrillation is receiving warfarin (Coumadin) therapy. Which laboratory result indicates that the therapy is effective?

• A. International normalized ratio (INR) of 1.0.
• B. Prothrombin time (PT) of 12 seconds.
• C. Partial thromboplastin time (PTT) of 60 seconds.
• D. International normalized ratio (INR) of 2.5.

Correct answer: D

Rationale: An International Normalized Ratio (INR) of 2.5 indicates that warfarin therapy is within the therapeutic range for a client with atrial fibrillation. A lower INR (such as 1.0) would suggest subtherapeutic levels, risking blood clots. Prothrombin time (PT) and partial thromboplastin time (PTT) are not specific to monitoring warfarin therapy.

2. Which annual screening should the nurse include when planning eye health programs at a preschool?

• A. visual acuity
• B. red light reflex
• C. conjunctivitis
• D. glaucoma

Correct answer: A

Rationale: The correct answer is A: visual acuity. Screening for visual acuity is essential in preschoolers to identify any vision issues early on, such as nearsightedness or farsightedness, which may require corrective lenses or other interventions. Red light reflex (choice B) is a method used to assess the eyes for abnormalities, but it is not typically included in routine preschool eye health screenings. Conjunctivitis (choice C) is an eye infection and not a screening test. Glaucoma (choice D) is a condition more commonly associated with adults and the elderly, making it less relevant for preschool eye health programs.

3. The client with newly diagnosed type 1 diabetes mellitus is being taught about insulin administration by the nurse. Which statement indicates that the client needs further teaching?

• A. I will inject my insulin into my abdomen for the fastest absorption.
• B. I will rotate injection sites to prevent lipodystrophy.
• C. I will store my insulin in the refrigerator at all times.
• D. I will rotate injection sites to prevent lipodystrophy.

Correct answer: C

Rationale: The correct answer is C. Insulin should not be stored in the refrigerator at all times; it should be kept at room temperature when in use to avoid irritation at the injection site. Storing insulin in the refrigerator can cause it to thicken and may lead to discomfort upon injection. Choices A and D are correct statements as injecting insulin into the abdomen for faster absorption and rotating injection sites to prevent lipodystrophy are appropriate insulin administration techniques. Therefore, the client does not need further teaching on these aspects.

4. The community health nurse believes that immunization rates in a lower socioeconomic section of the city are probably below the target set by the state health department. What action should the nurse take first to intervene with this health problem?

• A. join a political action group that focuses attention on the issue in the local news media
• B. partner with a local children's hospital in setting up free 'shot' clinics in the neighborhood
• C. review current epidemiological population data that might document a low immunization rate
• D. call a meeting of citizens to inform them of the importance of having their children immunized

Correct answer: C

Rationale: The most appropriate initial action for the community health nurse to take when addressing low immunization rates in a lower socioeconomic area is to review current epidemiological data. By reviewing this data, the nurse can gather evidence that documents the low immunization rate in the community. This information is crucial to support the need for targeted interventions to increase immunization rates. Choices A, B, and D involve actions that may be important at later stages of intervention but are not the first step. Joining a political action group, partnering with a hospital for clinics, or holding a community meeting are all valuable strategies, but they should be based on evidence obtained from reviewing epidemiological data to ensure targeted and effective interventions.

5. The nurse is caring for a client with hyperthyroidism. Which assessment finding requires immediate intervention?

• A. Heart rate of 100 beats per minute.
• B. Blood pressure of 150/90 mm Hg.
• C. Respiratory rate of 24 breaths per minute.
• D. Weight loss of 5 pounds in one week.

Correct answer: D

Rationale: Weight loss of 5 pounds in one week in a client with hyperthyroidism is concerning as it may indicate severe hypermetabolism, leading to potential complications such as cardiac arrhythmias, muscle weakness, and other metabolic disturbances. Rapid weight loss in hyperthyroidism indicates an accelerated metabolic rate and increased energy expenditure, which can be detrimental to the client's health. The other assessment findings (heart rate of 100 beats per minute, blood pressure of 150/90 mm Hg, respiratory rate of 24 breaths per minute) are commonly seen in clients with hyperthyroidism and may not necessarily require immediate intervention unless they are significantly outside the normal range or causing distress to the client.
