Severe and extensive hemolysis causes which of the ff?
- A. Leg ulcers
- B. Shock
- C. Priapism
- D. Compromised growth
Correct Answer: B
Rationale: Severe and extensive hemolysis leads to the release of large amounts of hemoglobin into the bloodstream, causing hemoglobinemia. This can result in hemoglobinuria, leading to acute renal failure and ultimately shock. Shock is the correct answer as it is a severe consequence of extensive hemolysis. Leg ulcers (A) may occur in conditions like peripheral arterial disease. Priapism (C) is unrelated to hemolysis. Compromised growth (D) is not a common consequence of hemolysis.

A 27-year old adult is admitted for treatment of Crohn’s disease. Which information is most significant when the nurse assesses nutritional health?
- A. Anthropometric measurements
- B. dry skin
- C. bleeding gums
- D. facialrubor
Correct Answer: A
Rationale: The correct answer is A: Anthropometric measurements. This includes height, weight, and body mass index, which are crucial indicators of the nutritional status of a patient with Crohn's disease. It helps assess malnutrition, muscle wasting, and overall nutritional health. Dry skin (B), bleeding gums (C), and facial rubor (D) are not direct indicators of nutritional health in a patient with Crohn's disease. Dry skin may indicate dehydration, bleeding gums may suggest poor oral hygiene or gum disease, and facial rubor may be a sign of inflammation but are not specific to nutritional status.
Which of the ff. medications might be ordered to help control symptoms of multiple sclerosis, and possibly induce a remission?
- A. Acyclovir
- B. Thyrotropin
- C. ACTH
- D. Benadryl
Correct Answer: C
Rationale: Correct Answer: C - ACTH
Rationale:
1. ACTH (adrenocorticotropic hormone) can help control symptoms and induce remission in multiple sclerosis by reducing inflammation.
2. ACTH stimulates the production of cortisol, a natural anti-inflammatory hormone.
3. By reducing inflammation in the central nervous system, ACTH can help manage symptoms and promote remission.
Summary of other choices:
A: Acyclovir - Antiviral medication used to treat herpes infections, not effective for multiple sclerosis.
B: Thyrotropin - Hormone that stimulates thyroid function, not used in the treatment of multiple sclerosis.
D: Benadryl - Antihistamine used for allergies and itching, not indicated for multiple sclerosis management.
A client with colon cancer requires a permanent colostomy because of the tumor location. After surgery, the client must learn how to irrigate the colostomy. When irrigating, how far into the stoma should the client insert the lubricated catheter?
- A. 0.25” to 0.5”
- B. 2” to 4”
- C. 1” to 1.5”
- D. 5” to 7”
Correct Answer: C
Rationale: The correct answer is C: 1” to 1.5”. When irrigating a colostomy, the client should insert the lubricated catheter about 1” to 1.5” into the stoma. This depth allows for effective irrigation of the colon without causing discomfort or damage. Inserting the catheter too shallow (choice A) may not reach the colon, while inserting it too deep (choices B and D) can cause injury or perforation. Therefore, the optimal depth of 1” to 1.5” ensures proper irrigation while minimizing risks of complications.
.A client complains of urinary discomfort and a burning sensation while urinating. A urethral smear shows evidence of urethritis, and the client is prescribed antibiotics and instructed to drink 2-3 L of water daily. For which of the ff reasons is the client advised to drink the specified amount of water?
- A. It will help him overcome urinary incontinence
- B. It will promote renal blood flow and flush bacteria from the urinary tract
- C. It will help him eliminate urinary odors
- D. It will provide relief from pain and discomfort as a result of urinary tract infection DISTURBANCES IN FLUIDS AND ELECTROLYTES
Correct Answer: B
Rationale: Step 1: Antibiotics are prescribed to treat urethritis, indicating a bacterial infection in the urinary tract.
Step 2: Increasing water intake (2-3 L daily) promotes renal blood flow, dilutes urine, and helps flush out bacteria from the urinary tract, aiding in the elimination of infection.
Step 3: Adequate hydration helps prevent the formation of concentrated urine, reducing the risk of recurrent urinary tract infections.
Step 4: Therefore, choice B is correct as it directly addresses the underlying cause of the client's symptoms.
Summary: Choices A, C, and D are incorrect as they do not directly target the bacterial infection causing the urinary discomfort. Drinking water will not specifically help with incontinence, eliminate odors, or provide pain relief.
Choose the condition th₃a⁻t exhibits blood values with a low pH and a low plasma bicarbonate concentration:
- A. Respiratory acidosis
- B. Metabolic acidosis
- C. Respiratory alkalosis
- D. Metabolic alkalosis
Correct Answer: B
Rationale: Step-by-step rationale:
1. Metabolic acidosis is characterized by low pH and low plasma bicarbonate.
2. In this condition, there is an excess of acids or a loss of bicarbonate.
3. The kidneys are unable to adequately excrete acids or retain bicarbonate.
4. This leads to a decrease in bicarbonate levels and a decrease in pH.
5. Respiratory acidosis (A) is characterized by low pH and high CO2 levels.
6. Respiratory alkalosis (C) is characterized by high pH and low CO2 levels.
7. Metabolic alkalosis (D) is characterized by high pH and high bicarbonate levels.
Summary:
- Choice A is incorrect as it describes a condition with high CO2 levels.
- Choice C is incorrect as it describes a condition with high pH.
- Choice D is incorrect as it describes a condition with high bicarbonate levels.
- Choice B is correct as it accurately describes the characteristics of a condition with low pH
