The healthcare provider reviews the laboratory results of a client whose serum pH is 7.38. What does this value imply about the client's homeostasis?
- A. Alkalosis
- B. Acidosis
- C. Normal serum pH
- D. Incompatible with life
Correct Answer: C
Rationale: A pH of 7.38 falls within the normal range (7.35-7.45), indicating that the client's acid-base balance is adequately maintained. Choices A and B are incorrect as alkalosis and acidosis refer to abnormal pH levels. Choice D is incorrect as a pH of 7.38 within the normal range is compatible with life.

The nurse is teaching a client about the administration of a subcutaneous injection. Which site is most appropriate for this type of injection?
- A. Deltoid muscle
- B. Dorsogluteal muscle
- C. Ventrogluteal muscle
- D. Abdomen
Correct Answer: D
Rationale: The abdomen is a common site for subcutaneous injections due to its accessibility and ample subcutaneous tissue. Subcutaneous injections are typically given in areas with a layer of fat between the skin and muscle, such as the abdomen, to allow for slow and consistent absorption of the medication. The deltoid muscle is more appropriate for intramuscular injections, not subcutaneous. The dorsogluteal muscle and ventrogluteal muscle are also more suited for intramuscular injections, not subcutaneous.
How should the nurse assess for cyanosis in a client with dark skin who is in respiratory distress?
- A. Abnormal skin color changes in a client with dark skin cannot be determined
- B. Blanching the soles of the feet in a client with dark skin reveals cyanosis
- C. The lips and mucus membranes of a client with dark skin are dusky in color
- D. Cyanosis in a client with dark skin is seen in the sclera
Correct Answer: C
Rationale: Observing the lips and mucous membranes provides a reliable indicator of cyanosis in clients with dark skin tones. Choice A is incorrect because cyanosis can be assessed in clients with dark skin by observing other body areas. Choice B is incorrect as blanching the soles of the feet is not a relevant method for assessing cyanosis. Choice D is incorrect as cyanosis is not typically seen in the sclera in clients with dark skin.
A client with a urinary tract infection is prescribed antibiotics. What should the nurse inform the client about antibiotic therapy?
- A. It may interfere with oral contraceptive effectiveness
- B. It can cause drowsiness
- C. It should be taken with meals
- D. Completing the full course is crucial
Correct Answer: D
Rationale: Completing the full course of antibiotics is crucial to fully eradicate the infection and prevent the development of antibiotic resistance. Informing the client about the importance of finishing the prescribed course helps in ensuring the effectiveness of the treatment and reduces the risk of recurrence. Choice A is incorrect because antibiotics do not generally interfere with oral contraceptive effectiveness. Choice B is incorrect because drowsiness is not a common side effect of antibiotics. Choice C is incorrect because while some antibiotics may need to be taken with meals, it is not a universal rule for all antibiotics.
The mother of an 8-year-old boy tells the nurse that he fell out of a tree and hurt his arm and shoulder. Which assessment finding is the most significant indicator of possible child abuse?
- A. The child looks at the floor when answering the nurse's questions
- B. The mother's version of the injury is different from the child's version
- C. The child has several abrasions on the chest and legs
- D. The mother refuses to answer questions about family history
Correct Answer: B
Rationale: In cases of possible child abuse, discrepancies between the accounts given by the child and the parent are critical indicators. This inconsistency could suggest that the injury was not accidental and may be a result of abuse. Looking at the floor while answering questions or having abrasions on the body can be concerning but are not as direct indicators of abuse as conflicting stories between the child and the parent.
During a health screening, a client's blood pressure reads 160/100 mm Hg. What should the nurse recommend?
- A. Schedule a follow-up appointment
- B. Start making immediate dietary changes
- C. Begin an exercise program
- D. All of the above
Correct Answer: A
Rationale: A follow-up with a healthcare provider is necessary to assess and manage the newly identified hypertension. While dietary changes and exercise are important for managing high blood pressure, immediate lifestyle modifications without further evaluation by a healthcare provider may not be safe or effective. Option A is the most appropriate initial step to ensure proper assessment and management of the client's blood pressure. Therefore, choices B and C are incorrect in this scenario. Option D is also incorrect because not all options should be implemented without proper medical guidance.
