A nasal spray of desmopressin acetate (DDAVP) is used to treat which endocrine disorder of the pituitary gland?

Choice A reason:

Cardiac arrhythmia is a primary clinical manifestation of hyperkalemia. Hyperkalemia, defined as an elevated level of potassium in the blood, can significantly affect the electrical activity of the heart. This can lead to various types of arrhythmias, including bradycardia, ventricular tachycardia, and even cardiac arrest1. The presence of arrhythmias is a critical indicator of hyperkalemia and requires immediate medical attention to prevent life-threatening complications.

Choice B reason:

Seizures are not typically associated with hyperkalemia2. While severe electrolyte imbalances can potentially lead to neurological symptoms, seizures are more commonly linked to conditions such as hyponatremia (low sodium levels) or hypocalcemia (low calcium levels). Therefore, seizures are not a primary sign of hyperkalemia.

Choice C reason:

Dyspnea, or difficulty breathing, can occur in various medical conditions, including heart failure and respiratory disorders. While hyperkalemia can lead to muscle weakness and fatigue, which might indirectly affect breathing, dyspnea is not a primary clinical manifestation of hyperkalemia. The main concern with hyperkalemia is its effect on cardiac function.

Choice D reason:

Oliguria, or reduced urine output, is a symptom of acute renal failure but not specifically indicative of hyperkalemia. While acute renal failure can lead to hyperkalemia due to the kidneys’ inability to excrete potassium, oliguria itself is not a direct sign of hyperkalemia. The focus should be on the cardiac effects of elevated potassium levels

Choice A reason:

Cleansing the suture line, maintaining an upright position, and using arm restraints are crucial aspects of postoperative care for an infant after cleft lip repair. Cleansing the suture line helps prevent infection and promotes healing. Keeping the infant in an upright position reduces the risk of aspiration and helps with breathing. Arm restraints prevent the infant from touching or rubbing the surgical site, which could disrupt the healing process.

Choice B Reason:

Mouth irrigations and a prone position are not recommended for postoperative care after cleft lip repair. Mouth irrigations can be too harsh for the delicate surgical site, and a prone position (lying face down) can increase the risk of aspiration and breathing difficulties. Cleansing the suture line is important, but the other aspects of this choice are not suitable.

Choice C Reason:

Frequent oral suction and spoon feeding are not appropriate for an infant after cleft lip repair. Oral suction can be too aggressive and may damage the surgical site. Spoon feeding is not recommended as it can put pressure on the healing lip. Giving a teething toy is also not advisable as it can cause the infant to put objects in their mouth, potentially harming the surgical site.

Choice D Reason:

Arm restraints are indeed necessary to prevent the infant from touching the surgical site. However, postural drainage and mouth irrigations are not suitable for postoperative care after cleft lip repair. Postural drainage is not relevant to this condition, and mouth irrigations can be too harsh for the healing tissue.
