A nurse is preparing to administer lithium 300 mg PO every 8 hr. Available is lithium carbonate 150 mg capsules. How many capsules should the nurse administer per dose?

(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Hyperextended position, or backward bending of the neck, is the correct position for the client's neck during a bronchoscopy procedure with a rigid scope and general anesthesia. This position allows the provider to insert the scope through the mouth and into the trachea and bronchi, while avoiding injury to the teeth, tongue, or larynx. It also facilitates visualization of the airways and removal of foreign bodies or secretions.

b) Neutral position, or alignment of the head and neck with the spine, is not the correct position for the client's neck during a bronchoscopy procedure with a rigid scope and general anesthesia. This position may interfere with the insertion of the scope and cause damage to the oral structures or airways.
c) Extended position, or forward bending of the neck, is not the correct position for the client's neck during a bronchoscopy procedure with a rigid scope and general anesthesia. This position may obstruct the airway and make it difficult for the provider to insert the scope and access the bronchi.
d) Flexed position, or downward bending of the neck, is not the correct position for the client's neck during a bronchoscopy procedure with a rigid scope and general anesthesia. This position may compress the airway and prevent adequate ventilation and oxygenation of the client.

Intercostal retractions, or the inward movement of the chest wall between the ribs, are a sign of respiratory distress and hypoxia. They indicate increased work of breathing and reduced lung expansion, which are common in clients who have postoperative atelectasis. Atelectasis is a collapse of alveoli in a part of the lung, which impairs gas exchange and oxygenation.

a) Lethargy, or a state of reduced mental alertness and energy, is not a typical manifestation of hypoxia. It can be caused by other factors, such as pain, medication, infection, or electrolyte imbalance. Hypoxia usually causes restlessness, anxiety, or confusion.
b) Bradycardia, or a slow heart rate, is not a typical manifestation of hypoxia. It can be caused by other factors, such as medication, vagal stimulation, or heart block. Hypoxia usually causes tachycardia, or a fast heart rate, as the body tries to compensate for the low oxygen level.
d) Bradypnea, or a slow respiratory rate, is not a typical manifestation of hypoxia. It can be caused by other factors, such as medication, brain injury, or metabolic alkalosis. Hypoxia usually causes tachypnea, or a fast respiratory rate, as the body tries to increase oxygen intake and carbon dioxide elimination.
