A primary health care provider prescribes acetaminophen liquid 450 mg orally every 4 hours PRN for pain. The medication label reads 160 mg/5 mL. The nurse prepares how many milliliters (mL) to administer one dose? Fill in the blank and record your answer to the nearest whole number.
Correct Answer: 14 mL
Rationale: Use the formula for calculating medication dosages. Formula: Desired × Volume / Available = mL per dose. 450 mg × 5 mL / 160 mg = 14 mL.

A client who underwent peripheral arterial bypass surgery 16 hours ago reports that there is increasing pain in the leg that worsens with movement and is accompanied by paresthesias. Based on these data, which action should the nurse take?
- A. Call the primary health care provider.
- B. Administer an opioid analgesic.
- C. Apply warm moist heat for comfort.
- D. Apply ice to minimize any developing swelling.
Correct Answer: A
Rationale: Compartment syndrome is characterized by increased pressure within a muscle compartment caused by bleeding or excessive edema. It compresses the nerves in the area and can cause vascular compromise. The classic signs of compartment syndrome are pain at rest that intensifies with movement and the development of paresthesias. Compartment syndrome is an emergency, and the primary health care provider is notified immediately because the client could require an emergency fasciotomy to relieve the pressure and restore perfusion.
A client has a total serum calcium level of 7.5 mg/dL (1.88 mmol/L). Which clinical manifestations should the nurse expect to note on assessment of the client? Select all that apply.
- A. Constipation
- B. Muscle twitches
- C. Negative Chvostek's sign
- D. Positive Trousseau's sign
- E. Hyperactive deep tendon reflexes
- F. Prolonged ST interval on electrocardiogram (ECG)
Correct Answer: B,D,E,F
Rationale: Hypocalcemia is a total serum calcium level less than 9 mg/dL (2.25 mmol/L). Clinical manifestations include muscle twitches, hyperactive deep tendon reflexes, positive Trousseau's sign, and prolonged ST interval on ECG. Negative Chvostek's sign and constipation are not associated with hypocalcemia.
The nurse provides a class to new mothers on newborn care. When teaching cord care, the nurse should instruct mothers to take which action?
- A. If antibiotic ointment has been applied to the cord, it is not necessary to do anything else to it.
- B. All that is necessary is to wash the cord with antibacterial soap and allow it to air-dry once a day.
- C. Apply alcohol thoroughly to the cord, being careful not to move the cord because it will cause pain to the newborn infant.
- D. Apply the prescribed cleansing agent to the cord, ensuring that all areas around the cord are cleaned two to three times a day.
Correct Answer: D
Rationale: The cord and base should be cleansed with alcohol (or another substance as prescribed) thoroughly, two to three times per day. The steps are (1) lift the cord; (2) wipe around the cord, starting at the top; (3) clean the base of the cord; and (4) fold the diaper below the umbilical cord to allow the cord to air-dry and prevent contamination from urine. Antibiotic ointment is not normally prescribed. Continuation of cord care is necessary until the cord falls off within 7 to 14 days. Water and soap are not necessary; in fact, the cord should be kept from getting wet. The infant does not feel pain in this area.
An assessment of a client's vocal cords requires indirect visualization of the larynx. Which instruction should the nurse give the client to facilitate this procedure?
- A. Try to swallow.
- B. Hold your breath.
- C. Breathe normally.
- D. Roll the tongue to the back of the mouth.
Correct Answer: C
Rationale: Indirect laryngoscopy is done to assess the function of the vocal cords or obtain tissue for biopsy. Observations are made during rest and phonation by using a laryngeal mirror, head mirror, and light source. The client is placed in an upright position to facilitate passage of the laryngeal mirror into the mouth and is instructed to breathe normally. Swallowing cannot be done with the mirror in place. The procedure takes longer than the time the client would be able to hold the breath, and this action is ineffective anyway. The tongue cannot be moved back because it would occlude the airway.
The nurse evaluates a client after treatment for carbon monoxide poisoning following a burn injury. The nurse should document that the treatment was effective if which finding was present? Select all that apply.
- A. The client is sleeping soundly.
- B. The client is awake and talking.
- C. Respiratory rate is 26 breaths/minute.
- D. The client's heart rate is 84 beats/minute.
- E. Carboxyhemoglobin levels are less than 5%.
- F. The heart monitor shows normal sinus rhythm.
Correct Answer: D,E,F
Rationale: Normal carboxyhemoglobin levels are less than 5% for a nonsmoking adult. Clients can be awake and talking with abnormally high levels. The symptoms of carbon monoxide poisoning are tachycardia, tachypnea, and central nervous system depression.
