Which of the following would the nurse teach the patient is the most common site for ear infections?
- A. Outer ear
- B. Middle ear
- C. Inner ear
- D. Semicircular canal
Correct Answer: B
Rationale: The correct answer is B, Middle ear. This is because the middle ear is the most common site for ear infections due to its anatomy, including the Eustachian tube that can easily become blocked, leading to fluid buildup and infection. The outer ear (A) is less susceptible to infections, while the inner ear (C) and semicircular canal (D) are not typically involved in ear infections, as they are more related to balance and hearing functions rather than infection susceptibility.

When teaching a client about insulin therapy, the nurse should instruct the client to avoid which over-the- counter preparation that can interact with insulin?
- A. Antacids
- B. Vitamins with irons
- C. Acetaminophen preparations
- D. Salicylate preparations
Correct Answer: D
Rationale: The correct answer is D: Salicylate preparations. Salicylate can potentiate the effects of insulin, leading to hypoglycemia. Therefore, the nurse should instruct the client to avoid this over-the-counter preparation when on insulin therapy. Antacids (A), vitamins with iron (B), and acetaminophen preparations (C) do not typically interact with insulin in a significant way.
The client is a type II DM patient. The client asks the nurse what is the primary reason a type II diabetic does not usually develop diabetic ketoacidosis?
- A. there is no insulin available for the state of hyperglycemia
- B. the type II diabetic has no protein of fat reserves
- C. there is no sufficient insulin to prevent the breakdown of protein and fatty acid for metabolic needs
- D. there is insufficient serum glucose concentrations
Correct Answer: C
Rationale: Rationale for Choice C (Correct answer):
- In type II DM, there is some insulin present but it is insufficient to meet the body's needs.
- Without sufficient insulin, the body turns to breaking down protein and fatty acids for energy.
- This leads to the formation of ketones, which can lead to diabetic ketoacidosis (DKA).
- Therefore, the primary reason a type II diabetic does not usually develop DKA is due to insufficient insulin to prevent the breakdown of protein and fatty acids for metabolic needs.
Summary of other choices:
- Choice A is incorrect because there is some insulin available in type II DM, though it may be insufficient.
- Choice B is incorrect as type II diabetics do have fat and protein reserves.
- Choice D is incorrect as insufficient serum glucose concentrations do not directly relate to the development of DKA in type II DM.
Which patient would benefit most from a capped IV catheter that is used intermittently rather than continuously?
- A. The patient with pneumonia who needs fluids and antibiotics.
- B. The patient who has had major blood loss after a motor vehicle accident.
- C. The young child who is dehydrated.
- D. The elderly patient who is receiving a diuretic for fluid overload.
Correct Answer: D
Rationale: The correct answer is D, the elderly patient receiving a diuretic for fluid overload. This patient would benefit most from a capped IV catheter used intermittently because diuretics can lead to fluctuations in fluid balance that require careful monitoring and adjustment of IV fluids. By using the catheter intermittently, healthcare providers can better control the amount of fluid administered to prevent electrolyte imbalances.
Option A is incorrect because a patient with pneumonia requiring fluids and antibiotics would likely benefit from a continuous IV to maintain stable levels of medications and hydration. Option B is incorrect as a patient with major blood loss would require continuous IV fluids to restore blood volume. Option C is incorrect as a dehydrated young child would also benefit from continuous IV fluids to rehydrate effectively.
The nurse is instructing a client with newly diagnosed hypoparathyroidism about the regimen used to treat this disorder. The nurse should state that the physician probably will prescribe daily supplements of calcium and:
- A. Folic acid
- B. Potassium
- C. Vitamin D
- D. Iron
Correct Answer: C
Rationale: The correct answer is C: Vitamin D. In hypoparathyroidism, there is a deficiency of parathyroid hormone leading to low calcium levels. Vitamin D helps in the absorption of calcium from the intestines, thus aiding in maintaining normal calcium levels. It is often prescribed along with calcium supplements to support bone health and prevent complications. Folic acid (A) is not directly related to the treatment of hypoparathyroidism. Potassium (B) is not typically prescribed for this condition and can be harmful in high levels. Iron (D) is not directly involved in calcium metabolism and is not part of the standard treatment regimen for hypoparathyroidism.
Which of the ff. nursing diagnoses is the focus of care for a patient with hypertension?
- A. Activity intolerance
- B. Impaired physical mobility
- C. Ineffective airway clearance
- D. Deficient knowledge
Correct Answer: D
Rationale: The correct answer is D: Deficient knowledge. This nursing diagnosis is appropriate because educating the patient about hypertension, its management, lifestyle modifications, and medication adherence is crucial in improving outcomes. Activity intolerance (A) and impaired physical mobility (B) are not typically primary focuses for hypertension but may be secondary concerns. Ineffective airway clearance (C) is unrelated to hypertension. Therefore, D is the most relevant option for addressing the patient's needs.
