A client with chronic obstructive pulmonary disease (COPD) is receiving oxygen therapy. Which finding indicates that the therapy is effective?
- A. The client is able to expectorate secretions easily.
- B. The client's oxygen saturation is 92%.
- C. The client's respiratory rate is 20 breaths per minute.
- D. The client's arterial blood gases show a pH of 7.35.
Correct Answer: C
Rationale: In a client with COPD receiving oxygen therapy, an effective response is indicated by a respiratory rate of 20 breaths per minute. This suggests that the client is effectively oxygenating while maintaining an appropriate respiratory rate. Choices A, B, and D are incorrect because expectorating secretions easily, having an oxygen saturation of 92%, and arterial blood gases showing a pH of 7.35 are not specific indicators of the effectiveness of oxygen therapy in COPD. Oxygen saturation of 92% may still be suboptimal in COPD, and arterial blood gases showing a pH of 7.35 may not necessarily reflect the overall effectiveness of oxygen therapy.

A client with a history of peptic ulcer disease is admitted with sudden severe abdominal pain. Which finding indicates the possibility of a perforated ulcer?
- A. Bowel sounds are hyperactive in all quadrants.
- B. Abdomen is soft and nondistended.
- C. The client reports sudden severe abdominal pain.
- D. Blood pressure of 110/70 mm Hg.
Correct Answer: C
Rationale: The correct answer is C. Sudden severe abdominal pain is a key clinical manifestation of a perforated ulcer. The sudden onset of severe pain is concerning for a perforation in the ulcer, which can lead to peritonitis if not promptly addressed. Choices A, B, and D are incorrect because hyperactive bowel sounds, a soft and nondistended abdomen, and a blood pressure of 110/70 mm Hg are not specific indicators of a perforated ulcer. Hyperactive bowel sounds may suggest increased gastrointestinal motility, a soft abdomen may not necessarily indicate a perforation, and a blood pressure of 110/70 mm Hg is within normal limits and does not directly relate to a perforated ulcer.
The healthcare professional is conducting a community assessment to identify health needs. Which method is most effective for gathering comprehensive data?
- A. conducting focus groups with community members
- B. reviewing local health department reports
- C. surveying healthcare providers in the area
- D. analyzing hospital admission records
Correct Answer: A
Rationale: Conducting focus groups with community members is the most effective method for gathering comprehensive data during a community assessment. This approach allows direct interaction with community members, fostering in-depth discussions that provide insights into the specific health needs and concerns of the community. Choice B, reviewing local health department reports, may offer valuable data but might not capture the nuanced perspectives and experiences of community members. Choice C, surveying healthcare providers, provides insights from a professional standpoint but may not fully represent the community's diverse health needs. Choice D, analyzing hospital admission records, offers information on healthcare utilization but may overlook important social determinants of health and community-specific issues that can only be addressed through direct engagement with community members.
The nurse is caring for a client with liver cirrhosis. Which assessment finding requires immediate intervention?
- A. Jaundice.
- B. Ascites.
- C. Peripheral edema.
- D. Spider angiomas.
Correct Answer: D
Rationale: Spider angiomas are abnormal clusters of blood vessels near the skin surface and can be indicative of an underlying liver condition. In the context of liver cirrhosis, spider angiomas can suggest portal hypertension and liver dysfunction, which requires immediate intervention. Jaundice (choice A) is a common manifestation of liver cirrhosis but not typically an immediate intervention priority unless severe. Ascites (choice B) and peripheral edema (choice C) are also common in liver cirrhosis but do not require immediate intervention unless they are causing respiratory compromise or other urgent issues.
The healthcare provider is assessing a client who has a new arteriovenous fistula in the left arm for hemodialysis. Which finding requires immediate intervention?
- A. A thrill is palpable on the fistula.
- B. The client's arm is warm and red.
- C. The fistula has a bruit on auscultation.
- D. There is no bruit on auscultation.
Correct Answer: B
Rationale: The correct answer is B. Warmth and redness in the client's arm suggest infection or thrombosis of the arteriovenous fistula, which requires immediate intervention to prevent complications. A thrill (A) is a normal finding in a functional arteriovenous fistula, indicating good blood flow. A bruit (C) is also a normal finding on auscultation of a functioning arteriovenous fistula, indicating proper blood flow. The absence of a bruit (D) may indicate a non-functioning fistula, which would need further evaluation but does not require immediate intervention as warmth and redness do.
During a home visit, the nurse observes that an elderly client has numerous bruises on her arms and appears fearful of her caregiver. What should the nurse do first?
- A. report the findings to adult protective services
- B. ask the client how she got the bruises
- C. document the observations in the client's medical record
- D. discuss the observations with the caregiver
Correct Answer: B
Rationale: The initial step for the nurse should be to ask the client how she got the bruises. This approach allows the nurse to directly assess the situation, gather information from the client, and potentially uncover signs of abuse. Reporting to adult protective services should come after obtaining more details from the client to ensure appropriate action. Documenting the observations is important but should follow gathering information from the client. Discussing the observations with the caregiver may not be appropriate as the caregiver could be the source of abuse, and involving them first may jeopardize the client's safety.
