Nursing Elites

1. The nurse should plan to evaluate the earliest onset of effectiveness of nitroglycerin (Nitrostat) sublingual (SL) within what time frame?

• A. 15 seconds
• B. 3 minutes
• C. 5 minutes
• D. 15 minutes

Correct answer: B

Rationale: The onset of action for Nitrostat SL is 1 to 3 minutes. Therefore, the nurse should plan to evaluate the earliest onset of effectiveness within 3 minutes after administering the medication. Option A, 15 seconds, is too short of a time frame for the onset of action of Nitrostat. Option C, 5 minutes, is slightly delayed compared to the typical onset time. Option D, 15 minutes, is too long to wait for evaluating the effectiveness of Nitrostat sublingual administration.

2. The PN is caring for a client with diabetes insipidus. The nurse can expect the lab work to show:

• A. elevated urine osmolarity and elevated serum osmolarity.
• B. decreased urine osmolarity and decreased serum osmolarity.
• C. elevated urine osmolarity and decreased serum osmolarity.
• D. decreased urine osmolarity and elevated serum osmolarity.

Correct answer: D

Rationale: In diabetes insipidus, the pituitary releases too much antidiuretic hormone (ADH), causing the client to produce a large amount of dilute urine (decreased osmolarity) and leading to dehydration (elevated serum osmolarity). Therefore, the correct answer is decreased urine osmolarity and elevated serum osmolarity. Choice C, elevated urine osmolarity and decreased serum osmolarity, is incorrect for diabetes insipidus, as it is more characteristic of syndrome of inappropriate ADH (SIADH). Choices A and B, elevated urine osmolarity and elevated serum osmolarity, and decreased urine osmolarity and decreased serum osmolarity, respectively, are generally not seen in diabetes insipidus, as urine and serum osmolarity typically move in opposite directions in this condition.

3. For a client with suspected appendicitis, in which quadrant should the nurse expect to find abdominal tenderness?

• A. upper right
• B. upper left
• C. lower right
• D. lower left

Correct answer: C

Rationale: The correct answer is C: lower right. Abdominal tenderness in the lower-right quadrant is a classic sign of appendicitis. The appendix is located in the lower right abdomen, so inflammation of the appendix typically causes tenderness in this specific area. Choices A, B, and D are incorrect because tenderness in the upper right, upper left, and lower left quadrants, respectively, is not typical in appendicitis cases. Therefore, the nurse should focus on assessing the lower right quadrant for tenderness when suspecting appendicitis.

4. Assessment of the client with an arteriovenous fistula for hemodialysis should include:

• A. inspection for visible pulsations.
• B. palpation of thrill.
• C. percussion for dullness.
• D. auscultation of blood pressure.

Correct answer: B

Rationale: The correct answer is to palpate for a thrill. A thrill should be present in a functioning arteriovenous fistula (AVF) and indicates good blood flow. The client should be educated to check for this sensation daily at home to monitor the AVF's patency. Visible pulsations are not typically observed in an AVF. Percussion for dullness does not provide relevant information about the AVF. Auscultation of blood pressure is not a standard practice in assessing an AVF. However, auscultation of the AVF for a bruit, a sound indicating turbulent blood flow, is crucial in evaluating the AVF's patency.

5. The nurse is caring for a 44-year-old client diagnosed with hypoparathyroidism. Which electrolyte imbalance is closely associated with hypoparathyroidism?

• A. Hypocalcemia.
• B. Hyponatremia.
• C. Hyperkalemia.
• D. Hypophosphatemia.

Correct answer: A.

Rationale: The correct answer is Hypocalcemia. In hypoparathyroidism, where the parathyroid glands are not producing sufficient parathyroid hormone, calcium levels become inadequate. This leads to hypocalcemia, characterized by symptoms such as muscle spasms, anxiety, seizures, hypotension, and congestive heart failure. Hyponatremia and hyperkalemia are not typically associated with hypoparathyroidism. While hyperphosphatemia can be seen in hypoparathyroidism due to decreasing calcium levels, the question specifically asks about the primary electrolyte imbalance closely related to hypoparathyroidism, which is hypocalcemia.
