The nurse is performing a physical assessment of a client with a history of smoking and notes a barrel chest. Which action is most important for the nurse to take next?

A. Assess the client's oxygen saturation level

B. Teach the client pursed-lip breathing techniques

C. Determine the client's history of lung disease

D. Obtain an arterial blood gas sample

Correct Answer: A
Rationale: Corrected Rationale: Assessing the client's oxygen saturation level is crucial when a nurse identifies a barrel chest. A barrel chest is often associated with chronic obstructive pulmonary disease (COPD), which can lead to impaired gas exchange and decreased oxygen saturation. Monitoring the oxygen saturation level will provide immediate information on the client's respiratory status. Teaching pursed-lip breathing techniques, determining lung disease history, and obtaining arterial blood gas samples are important interventions but assessing oxygen saturation takes precedence in this scenario due to its direct impact on the client's respiratory function.

A client who has had three spontaneous abortions is requesting information about possible causes. The nurse's response should be based on which information?

• A. Chromosomal abnormalities are the most common cause of early spontaneous abortions
• B. Incompetent cervix can cause spontaneous abortions
• C. An infection can cause spontaneous abortions
• D. Nutritional deficiencies are the most common cause of early spontaneous abortions

Correct Answer: A
Rationale: The correct answer is A: Chromosomal abnormalities are the most common cause of early spontaneous abortions. Spontaneous abortions, also known as miscarriages, often occur due to chromosomal abnormalities in the fetus. These abnormalities are a common cause of early pregnancy loss. Choice B is incorrect because an incompetent cervix typically leads to late miscarriages, not early spontaneous abortions. Choice C is incorrect as while infections can be a cause of spontaneous abortions, they are not the most common cause. Choice D is incorrect as nutritional deficiencies are not the most common cause of early spontaneous abortions.

The nurse is performing a physical assessment of a male client who has chronic renal failure. Which assessment finding is most important for the nurse to report to the healthcare provider?

• A. Client reports difficulty breathing
• B. Client reports shortness of breath when lying flat
• C. Client reports swelling in the feet and ankles
• D. Client reports a metallic taste in the mouth

Correct Answer: A
Rationale: In a client with chronic renal failure, difficulty breathing is the most critical finding to report. This symptom may indicate fluid overload or pulmonary edema, which can be life-threatening. Shortness of breath when lying flat (orthopnea) is also concerning but less urgent than difficulty breathing. Swelling in the feet and ankles (edema) is a common finding in renal failure but may not be as immediately critical as difficulty breathing. A metallic taste in the mouth is associated with uremia, a common complication of chronic renal failure, but it is not as urgent as respiratory distress.

The client diagnosed with a right fractured femur has skeletal traction applied to the right femur. Which interventions should the nurse implement?

• A. Perform passive range of motion to the right leg
• B. Remove skeletal weights every shift to assess right leg
• C. Turn frequently from prone to supine positions
• D. Maintain skeletal pin sites and assess for signs of infection

Correct Answer: D
Rationale: Maintaining skeletal pin sites and assessing for infection are critical in skeletal traction care.

A nurse is planning care for a client who has a new prescription for metoprolol (Lopressor). Which assessment finding should the nurse report to the healthcare provider before administering the medication?

• A. Heart rate of 50 beats per minute
• B. Blood pressure of 90/60 mm Hg
• C. Respiratory rate of 20 breaths per minute
• D. Temperature of 99°F (37.2°C)

Correct Answer: A
Rationale: A heart rate of 50 beats per minute is a concerning finding that should be reported before administering metoprolol. Metoprolol is a beta-blocker that can further lower the heart rate, so a heart rate of 50 bpm indicates potential bradycardia, which is a contraindication for administering this medication. Choices B, C, and D are within normal ranges and do not pose immediate concerns related to metoprolol administration.
