Which serum blood finding in diabetic ketoacidosis alerts the nurse that immediate action is required?

Correct Answer: C

Rationale: A hematocrit (HCT) of 60 indicates severe dehydration, a critical condition in diabetic ketoacidosis that requires immediate intervention. Severe dehydration can lead to hypovolemic shock and organ failure. While a low pH below 7.3 is indicative of acidosis, it may not require immediate action compared to severe dehydration. A potassium level of 5.0 is within the normal range and not a critical finding in this scenario. PaO2 of 79% reflects oxygenation status, which is important but not the most critical finding requiring immediate action in diabetic ketoacidosis.

Correct Answer: A

Rationale: The initial action the nurse should take after discovering a client's eviscerated wound is to cover the incision with a moist sterile dressing. This step is crucial to protect the exposed tissue, prevent infection, and create a conducive environment for healing. While notifying the surgeon is important, addressing the wound immediately takes precedence. Assessing vital signs is essential but should follow the immediate intervention of covering the wound. Placing the client in a supine position with knees bent is not the priority in managing an eviscerated wound; the first step is to cover the wound to protect the exposed tissue.

Correct Answer: A

Rationale: The correct answer is A: Purulent. Purulent drainage is thick, yellow, and indicates the presence of infection. This type of drainage is typically seen in infected wounds. Choice B, Serous drainage, is thin, clear, and watery, which is normal in the initial stages of wound healing. Sanguineous drainage, choice C, is bright red and indicates fresh bleeding. Serosanguineous drainage, choice D, is pale pink to red and is a mixture of blood and serous fluid commonly seen in the early stages of wound healing.

Correct Answer: C

Rationale: The correct answer is C: Prothrombin time (PT). Prothrombin time is monitored to assess the therapeutic response to warfarin therapy. Warfarin works by inhibiting vitamin K-dependent clotting factors, which prolongs the PT. Monitoring PT helps determine if the client's blood is clotting within the desired therapeutic range. Choices A, B, and D are incorrect because bleeding time, coagulation time, and partial thromboplastin time are not specifically used to monitor the therapeutic response to warfarin. Bleeding time assesses platelet function, coagulation time is a general term and not a specific test, and partial thromboplastin time is more relevant in monitoring heparin therapy, not warfarin.

Correct Answer: B

Rationale: The correct answer is B because the nursing diagnosis of Impaired physical mobility is appropriate for a patient who has some limitations in mobility but is not completely immobile. Choice A is incorrect as a patient who is completely immobile would not have impaired physical mobility but rather no physical mobility at all. Choices C and D are also incorrect as they do not directly relate to the defining characteristics of Impaired physical mobility, which involve limitations in movement and physical activity.

Correct Answer: A

Rationale: The correct answer is A: A mole with an asymmetrical appearance. Asymmetry is a key characteristic of potential skin malignancy. An asymmetrical mole does not have a uniform shape when divided in half. This irregularity raises suspicion for skin cancer. Choices B, C, and D are incorrect. A mole with a regular border (B) is more likely to be benign. A mole that is the same color throughout (C) is also a feature commonly seen in benign moles. Additionally, a mole smaller than 6mm in diameter (D) is not necessarily indicative of malignancy, as some melanomas can be smaller or larger than this size.

Correct Answer: A

Rationale: Cheddar cheese is the correct answer as it is a good source of complete protein that contains all essential amino acids required for maintaining a positive nitrogen balance for wound healing. Complete proteins provide all essential amino acids needed by the body. White rice, apples, and green beans do not offer complete proteins like cheddar cheese, making them inadequate choices for this purpose.

Correct Answer: A

Rationale: The nurse should prioritize seeing the client who has new onset dyspnea 24 hours after a total hip arthroplasty first. This sudden dyspnea could indicate a serious complication like a pulmonary embolism, which requires immediate assessment and intervention. Acute abdominal pain, a UTI with a low-grade fever, and pneumonia with an oxygen saturation of 96% are important concerns but are not as immediately life-threatening as potential pulmonary embolism indicated by sudden dyspnea postoperatively.

Correct Answer: C

Severe dehydration can lead to hypovolemic shock and organ failure. While a low pH below 7.3 is indicative of acidosis, it may not require immediate action compared to severe dehydration.
