A patient complains of tingling in his fingers. He has positive Trousseau's and Chvostek's signs. He says that he feels depressed. Choose the most likely serum calcium (Ca ) value for this patient:

  • A. 11mg/dl
  • B. 7mg/dl
  • C. 9mg/dl
  • D. 5mg/dl
Correct Answer: A

Rationale: The patient's symptoms of tingling in the fingers, positive Trousseau's and Chvostek's signs, and feeling depressed are suggestive of hypocalcemia, which is commonly associated with low serum calcium levels. In this case, the most likely serum calcium value would be below the normal range, which is around 8.5-10.5 mg/dl. Among the given choices, an extremely low calcium value of 5mg/dl (Choice D) would be more consistent with severe hypocalcemia presenting with tetany and other neuromuscular symptoms rather than depression and mild symptoms. On the other hand, a high calcium level of 11mg/dl (Choice A) would indicate hypercalcemia, which can lead to neuropsychiatric symptoms like depression, as seen in this patient's presentation. Therefore, Choice A (11mg/dl) is the most likely serum calcium value for

The patient is dangling at the bedside and states, "Oh, my stomach is tearing open." Which of the following actions should the nurse immediately take when dehiscence occurs?

  • A. Have patient sit upright in a chair.
  • B. Have patient lie down.
  • C. Slow IV fluids.
  • D. Obtain a sterile suture set.
Correct Answer: B

Rationale: When dehiscence, which is the separation of the layers of a surgical incision, occurs in a patient, it is important to have the patient lie down. This position will help decrease intra-abdominal pressure and reduce the risk of further complications. Having the patient sit upright in a chair can increase intra-abdominal pressure, worsening the dehiscence. Slowing IV fluids may be necessary to prevent fluid overload in certain situations, but it is not the immediate action required when dehiscence occurs. Obtain a sterile suture set may eventually be needed, but the priority in this situation is to stabilize the patient by having them lie down.

A 13-year-old is worried because his breasts are growing and are tender. What should the nurse tell him?

  • A. We will draw blood to determine the cause.
  • B. It is a slight hormonal imbalance that can be corrected with medication.
  • C. It is a normal condition of puberty (gynecomastia) that usually resolves within a year or two.
  • D. It is a rare finding in boys during puberty.
Correct Answer: C

Rationale: Gynecomastia and breast tenderness occur in about one-third of boys during mid-puberty and usually resolve within 2 years.

Why should the nurse closely monitor older adults when they are receiving IV therapy? Choose all that apply

  • A. Because their defense mechanisms are less efficient
  • B. Because they are prone to fluid overload
  • C. Because they are prone to reduced renal efficiency
  • D. Because they have inadequate intake of dietary fiber
Correct Answer: E

Rationale: Older adults should be closely monitored when receiving IV therapy because their defense mechanisms are less efficient (A) as they age, making them more susceptible to infections and complications from invasive procedures like IV therapy. Additionally, older adults are prone to reduced renal efficiency (C), which can affect their ability to excrete excess fluids and electrolytes properly. Monitoring for signs of fluid overload and renal impairment is crucial in this population to prevent adverse outcomes related to IV therapy.

The statement about sleep which is NOT true is

  • A. melatonin is secreted in dark-light cycle
  • B. slow-wave sleep is needed for brain injury protection
  • C. rapid eye movement (REM) sleep is responsible for dreams
  • D. both REM and non-REM cycles are sufficient for sleep
Correct Answer: B

Rationale: Slow-wave sleep is primarily restorative, not protective against brain injury.

Why must a nurse measure the intake and output and recommend a daily fluid intake of approximately 3000 to 4000 mL for a client with pyelonephritis?

  • A. To determine the clients response to the therapy
  • B. To flush out the infectious microorganisms from the urinary tract
  • C. To determine the location of discomfort
  • D. To detect any evidence of changes#
Correct Answer: B

Rationale: A nurse measures the intake and output and recommends a daily fluid intake of approximately 3000 to 4000 mL for a client with pyelonephritis primarily to help flush out the infectious microorganisms from the urinary tract. Pyelonephritis is a bacterial infection of the kidneys and urinary tract, and increasing fluid intake can help dilute the urine and increase urine output, which may help wash out and eliminate the infectious microorganisms causing the infection. Adequate hydration also helps the kidneys function optimally in eliminating waste and toxins from the body. Therefore, maintaining a high fluid intake is crucial in the management of pyelonephritis to support the body's natural defense mechanisms and aid in recovery.
