A nurse assesses a patient who is prescribed a medication that inhibits aldosterone secretion and release. For which potential complications will the nurse assess? (Select all that apply.)
A. Serum potassium level of 3.2 mEq/L
A serum potassium level of 3.2 mEq/L indicates hypokalemia, which is a potential complication of inhibiting aldosterone secretion and release. Aldosterone plays a key role in potassium regulation in the body by promoting potassium excretion in the kidneys. When aldosterone secretion is inhibited, potassium excretion decreases, leading to an accumulation of potassium in the bloodstream and resulting in hypokalemia. Symptoms of hypokalemia may include muscle weakness, cramping, irregular heartbeat, and fatigue.
B. Urine output of 1 200 mL in the last 2 hours
Urine output of 1,200 mL in the last 2 hours:This option does not directly relate to complications of inhibiting aldosterone secretion. A urine output of 1,200 mL in the last 2 hours indicates adequate urine production, which is generally a positive sign. However, in the context of inhibiting aldosterone secretion, the nurse would be more concerned about decreased urine output due to potential renal effects.
C. Blood osmolality of 250 mOsm/kg (250 mmol/kg)
Blood osmolality of 250 mOsm/kg (250 mmol/kg):Blood osmolality within the normal range (usually around 275-295 mOsm/kg) is not directly associated with complications of inhibiting aldosterone secretion. Blood osmolality reflects the concentration of solutes in the blood and is regulated by various factors, including water balance, electrolyte levels, and hormonal regulation. Inhibiting aldosterone secretion primarily affects electrolyte balance rather than blood osmolality.
D. Urine output of 25 mL/hr
Urine output of 25 mL/hr:A urine output of 25 mL/hr is considered low and may indicate decreased renal perfusion or impaired kidney function. Inhibiting aldosterone secretion can affect renal function and urine output, leading to decreased urine production. Reduced urine output can contribute to fluid and electrolyte imbalances and may be a concern in patients with inhibited aldosterone secretion.
E. Serum potassium level of 5.4 mEq/L:
A serum potassium level of 5.4 mEq/L indicates hyperkalemia, which is another potential complication of inhibiting aldosterone secretion. Aldosterone helps regulate potassium levels by promoting potassium excretion in the kidneys. When aldosterone secretion is inhibited, potassium excretion decreases, leading to an accumulation of potassium in the bloodstream and resulting in hyperkalemia. Symptoms of hyperkalemia may include muscle weakness, irregular heartbeat, nausea, and numbness or tingling.

Similar Questions
A nurse is caring for a client who is 1 day postoperative following an open thoracotomy. The client is receiving oxygen mist at 40% by face tent. The client's SPO2 is 89-96%. ABG results are: pH 7.31, PaO2 93 mm Hg, PCO2 5O mm Hg, HCO3 25 mEq/L. Which of the following is an appropriate action by the nurse?
A. Position the client prone and have the respiratory therapist perform postural drainage.
Prone positioning and postural drainage are typically not appropriate interventions for a client 1 day postoperative following an open thoracotomy, as this could place stress on the incision site and cause discomfort or injury.
B. Place the client in high-Fowler's position and encourage the use of incentive spirometer and coughing.
High-Fowler's position facilitates lung expansion, which can improve ventilation and oxygenation. Encouraging the use of an incentive spirometer and promoting coughing helps clear secretions and expand the lungs, addressing the mild respiratory acidosis indicated by the ABG results (pH 7.31 and PaCO2 50 mm Hg).
C. Increase oxygen to 70%.
Increasing oxygen to 70% is not appropriate, as the PaO2 level is within normal limits (93 mm Hg). The client's issue appears to be related more to ventilation (indicated by the elevated PaCO2) rather than oxygenation, so additional oxygen would not address the underlying cause and could lead to oxygen toxicity if used long-term.
D. Switch oxygen to a nonrebreather mask.
A nonrebreather mask delivers a high concentration of oxygen, which is not necessary in this case since the client’s PaO2 is already adequate. The primary issue is not a lack of oxygen but rather the retention of CO2, so promoting ventilation and lung expansion through positioning and respiratory exercises is more appropriate.

A nurse is caring for a client who has burns to approximately 50% of their body. Which of the following physiological changes related to the burns should the nurse anticipate? (Select all that apply.)
A. Decreased plasma volume
Burn injuries cause a significant inflammatory response, leading to fluid shifts from the intravascular space to the interstitial space. This results in hypovolemia and decreased plasma volume, especially during the acute phase of burns.
B. Diuresis
Diuresis typically occurs after fluid resuscitation and stabilization of the client (in the later phase of burn recovery). In the initial phase, oliguria is more common due to hypovolemia and reduced renal perfusion.
C. Hypermagnesemia
Hypermagnesemia is not typically associated with burn injuries. Instead, clients with burns often experience hypomagnesemia due to fluid shifts, protein loss, and increased renal losses.
D. Capillary leak
Burn injuries lead to a systemic inflammatory response, causing capillary leak syndrome. This increases vascular permeability, allowing fluid, electrolytes, and proteins to leak into the interstitial spaces, contributing to edema and hypovolemia.
E. Loss of protein
Proteins are lost through damaged capillaries and open burn wounds, contributing to decreased oncotic pressure, edema, and a need for aggressive nutritional support to promote healing and recovery.

A nurse is assisting in identifying clients on the medical surgical floor with skin problems. Which of the following are most likely to become chronic wounds?
A. Cluster of oral herpes sores
Cluster of oral herpes sores: Oral herpes sores typically heal within a few weeks and do not generally become chronic wounds unless there are complications or underlying immune system issues. They are more acute in nature and tend to resolve without becoming chronic.
B. Abdominal surgical incision
Abdominal surgical incision: Surgical incisions are designed to heal within a specific timeframe, usually a few weeks to a couple of months, depending on the type of surgery and individual healing factors. While surgical wounds can sometimes have delayed healing or complications, they are not typically categorized as chronic wounds unless they fail to heal or become recurrent over an extended period.
C. Diabetic foot ulcer
Diabetic foot ulcer: Diabetic foot ulcers are highly prone to becoming chronic wounds due to the underlying pathology associated with diabetes, such as neuropathy (nerve damage), peripheral vascular disease (poor circulation), and impaired immune function. These factors can impair the normal healing process, leading to delayed healing, infection, and the potential for the wound to become chronic if not managed appropriately.
D. Posterior scalp wound
Posterior scalp wound: Scalp wounds can heal relatively quickly, especially with proper wound care and management. However, certain factors such as the size of the wound, depth, presence of infection, and underlying conditions can influence the likelihood of a scalp wound becoming chronic. In general, scalp wounds are less likely to become chronic compared to wounds in areas with higher risk factors, such as diabetic foot ulcers.
