Approximately how much fluid is lost in acute weight loss of .5kg?
- A. 50 ml
- B. 750 ml
- C. 500 ml
- D. 75 ml
Correct Answer: C
Rationale: The correct answer is C: 500 ml. When someone loses 0.5 kg of weight, it is estimated that about 500 ml of fluid has been lost, as 1 kg of body weight is roughly equivalent to 1 liter of fluid. This fluid loss is due to water loss through sweating, breathing, and urine. Choice A (50 ml) is too small of an amount for a significant weight loss. Choice B (750 ml) is too high and would correspond to a larger weight loss. Choice D (75 ml) is also too small to account for a 0.5 kg weight loss.

Which of the ff should a client with auto immune disorder be advised to avoid?
- A. Resting during the periods of severe exacerbation
- B. Regular exercise during the periods of remission
- C. Being in crowds during the periods of immunosuppression
- D. Humid environment during the periods of remission
Correct Answer: C
Rationale: The correct answer is C: Being in crowds during the periods of immunosuppression. Clients with autoimmune disorders have compromised immune systems, making them more susceptible to infections. Being in crowds increases the risk of exposure to various pathogens, potentially leading to infections. Avoiding crowds during periods of immunosuppression helps minimize the risk of infections.
A: Resting during the periods of severe exacerbation is important for managing symptoms and conserving energy, but it is not specifically related to avoiding triggers for autoimmune disorders.
B: Regular exercise during the periods of remission is beneficial for overall health and can help manage autoimmune disorders, as long as it is appropriate and not excessive.
D: Humid environments during the periods of remission do not directly impact autoimmune disorders unless the individual has a specific sensitivity to humidity.
A patient is admitted who has had severe vomiting for 24 hours. She states that she is exhausted and weak. The results of an admitting ECG show flat T waves and ST segment depression. Choose the most likely potassium (K ) value for this patient.
- A. 4.0mEq/L
- B. 2.0mEq/L
- C. 8.0mE⁺q/L
- D. 2.6mEq/L
Correct Answer: B
Rationale: The correct answer is B: 2.0mEq/L. Severe vomiting can lead to hypokalemia, characterized by flat T waves and ST segment depression on ECG. This is due to decreased potassium levels affecting cardiac repolarization. A potassium level of 2.0mEq/L is dangerously low and consistent with the ECG findings in this scenario. Choices A, C, and D have potassium levels that are not reflective of severe hypokalemia, therefore they are incorrect. Option A (4.0mEq/L) is within the normal range, option C (8.0mEq/L) is elevated, and option D (2.6mEq/L) is higher than the correct value of 2.0mEq/L.
Several days before admission, a client reports finding a small lump in the left breast near the nipple. What should the nurse tell the client to do?
- A. Inform the physician immediately
- B. Squeeze the nipple to check for drainage
- C. Check the area after the next menstrual period
- D. Put a heating pad on the area to reduce inflammation
Correct Answer: A
Rationale: The correct answer is A: Inform the physician immediately. This is because finding a lump in the breast could be a sign of breast cancer, and early detection is crucial for effective treatment. The nurse should advise the client to seek medical evaluation promptly for further assessment, such as a mammogram or biopsy.
Choice B is incorrect because squeezing the nipple could potentially worsen the condition or spread cancerous cells if present. Choice C is incorrect as waiting until after the next menstrual period may delay necessary medical attention. Choice D is incorrect as using a heating pad could mask symptoms and delay proper diagnosis and treatment.
A 40 year-old female nurse had a fecal impaction and was admitted to the hospital. The physician orders an oil retention enema followed by a cleansing enema. What is the rationale for administering the oiul enema first?
- A. lubricate the walls of the intestinal tract
- B. soften the fecal mass and lubricate the walls of the rectum and colon
- C. reduce bacterial content of the fecal mass
- D. coat the walls of the intestines to prevent irritation by the hardened fecal mass
Correct Answer: B
Rationale: The correct answer is B: soften the fecal mass and lubricate the walls of the rectum and colon. First, the oil retention enema helps soften the fecal mass, making it easier to pass. Second, the oil lubricates the walls of the rectum and colon, reducing friction and making the passage of stool smoother. This helps prepare the fecal impaction for removal during the subsequent cleansing enema. Choices A, C, and D are incorrect because they do not directly address the primary goal of softening the fecal mass and lubricating the walls of the intestines to facilitate the removal of the impaction.
A client with a cerebellar brain tumor is admitted to an acute care facility. The nurse formulates a nursing diagnosis of Risk for injury. Which “related-to” phrase should the nurse add to complete the nursing diagnosis statement?
- A. Related to visual field deficits
- B. Related to impaired balance
- C. Related to difficulty swallowing
- D. Related to psychomotor seizures
Correct Answer: B
Rationale: The correct answer is B: Related to impaired balance. The rationale for this is that a client with a cerebellar brain tumor may experience impaired balance due to the cerebellum's role in coordinating voluntary movements and maintaining balance. Impaired balance increases the risk for falls and other injuries. Visual field deficits, difficulty swallowing, and psychomotor seizures are not directly related to the cerebellum's functions in balance and coordination. Therefore, these choices are incorrect for this specific nursing diagnosis.
