What do the following ABG values indicate: pH 7.38, PO2 78 mmHg, PCO2 36 mmHg, and HCO3 24 mEq/L?

Correct Answer: B

Rationale: The correct answer is 'homeostasis.' These ABG values fall within the normal range, indicating a state of balance and homeostasis. The pH is within the normal range (7.35-7.45), the PCO2 is normal (35-45 mmHg), and the HCO3 level is also normal (22-26 mEq/L). Choice A, 'metabolic alkalosis,' is incorrect because the pH, PCO2, and HCO3 levels are not indicative of metabolic alkalosis. Choice C, 'respiratory acidosis,' is incorrect as the pH and PCO2 values are not elevated. Choice D, 'respiratory alkalosis,' is incorrect as the pH and PCO2 levels are not decreased. Therefore, the ABG values provided do not correspond to any acid-base disturbance, confirming that the patient is in a state of homeostasis.

Correct Answer: C

Rationale: In this scenario, the client undergoing hemodialysis is experiencing symptoms like restlessness, a headache, and nausea. These symptoms are indicative of an air embolus, a serious complication that can occur during hemodialysis. Air embolus happens when air enters the bloodstream and can lead to symptoms like restlessness, a headache, and nausea. It is crucial for the nurse to suspect and address this complication promptly to prevent further harm to the client. Choices A and D (Infection) are less likely in this case, as the symptoms presented are more suggestive of an air embolus rather than an infection. Choice B (Disequilibrium syndrome) is also less likely as the symptoms described are not typical of this syndrome. Therefore, the correct answer is C: Air embolus.

Correct Answer: C

Rationale: The correct answer is sodium and chloride. These two electrolytes are the major components of extracellular fluid. Potassium and phosphate (Choice B) are not the major electrolytes in the extracellular fluid. Potassium is primarily an intracellular ion, and phosphate is more abundant in the intracellular fluid and bones. Sodium and phosphate (Choice D) are also not the major electrolytes in the extracellular fluid. Chloride plays a crucial role in maintaining electrolyte balance and is predominantly found in extracellular fluid alongside sodium.

Correct Answer: B

Rationale: The correct answer is B: meconium. Greenish amniotic fluid passed when the fetus is in a cephalic (head) presentation might indicate fetal distress. A fetus in the breech presentation passes meconium due to compression on the intestinal tract. Choice A, blood, is incorrect as blood in the amniotic fluid would present as a different color. Choice C, hydramnios, refers to an excess of amniotic fluid and would not cause the greenish coloration. Choice D, caput, is swelling of a newborn's scalp and is not related to the color of the amniotic fluid.

Correct Answer: A

Rationale: A contusion is a soft tissue injury caused by blunt force. It is an injury that does not break the skin, caused by a blow, and characterized by swelling, discoloration, and pain. The immediate application of cold might limit the development of a contusion. A strain is a muscle pull from overuse, overstretching, or excessive stress. A sprain is caused by a wrenching or twisting motion. A dislocation is a condition where the articular surfaces of the bones forming a joint are no longer in anatomical contact. Therefore, the correct answer is 'contusion' as it specifically relates to soft tissue injury caused by blunt force.

Correct Answer: D

Rationale: The correct answer is 'situational.' A situational crisis is an unexpected, unplanned event, such as the death of a spouse, which can lead to significant distress. Option A is incorrect because a maturational crisis is related to normal life transitions like getting married or retiring. Choices B and C are incorrect as they do not represent recognized crisis states in the context of the scenario provided.

Correct Answer: A

Rationale: The correct answer is to transfuse neutrophils (granulocytes) to prevent infection. Granulocyte transfusion is not routinely indicated to prevent infection in neutropenic clients. While neutrophils are essential in fighting infections and are beneficial in selected populations of infected, severely granulocytopenic clients who do not respond to antibiotics and are expected to experience prolonged suppression of granulocyte production, routine granulocyte transfusion is not recommended. Choices B, C, and D are appropriate interventions for a severely neutropenic client. Prohibiting fresh flowers and plants helps reduce the risk of exposure to environmental pathogens. Avoiding rectal suppositories minimizes the risk of introducing harmful bacteria. Excluding raw vegetables from the diet reduces the likelihood of foodborne infections.

Correct Answer: B

Rationale: The correct answer is B: secondary prevention. This type of prevention focuses on reducing the impact of a disease by early detection and treatment. In the case of gonorrhea, teaching the client how to prevent reinfection and further spread falls under secondary prevention because it aims to reduce the prevalence and morbidity of the disease. Choice A (primary prevention) involves measures to prevent the disease from occurring in the first place, such as vaccination. Choice C (tertiary prevention) focuses on managing the long-term consequences of a disease to prevent complications. Choice D (primary health care prevention) is not a recognized term in prevention strategies.

Correct Answer: D

Rationale: The correct answer is, "I have my wife examine the soles of my feet each day."? Clients with peripheral vascular disease should examine their feet daily for any signs of redness, dryness, or cuts. If the client is unable to do this themselves due to decreased sensation in their feet, a caregiver or family member should assist. Soaking feet in a hot tub should be avoided as the client may not be able to sense if the water is too hot, potentially causing burns. Walking barefoot can lead to injuries, so wearing shoes or slippers is recommended to minimize trauma. While quitting smoking is a positive step, using chewing tobacco can still constrict blood vessels, adversely affecting circulation in the extremities.
