Which of the following acid-base imbalances should the nurse expect?
A. Metabolic acidosis.
A respiratory rate of 9/min and shallow respirations are indicative of hypoventilation, which can lead to an accumulation of carbon dioxide (CO2) in the blood. This condition results in respiratory acidosis (
B. Respiratory alkalosis.
B) is characterized by a low PaCO2 and an elevated pH due to hyperventilation. Shallow respirations and a respiratory rate of 9/min do not align with this condition, as it typically involves rapid and deep breathing.
C. Metabolic alkalosis.
C) results from a primary excess of bicarbonate (HCO3-) in the blood and is not associated with the given respiratory patterns. Shallow respirations and a low respiratory rate are more likely to lead to an accumulation of CO2, causing respiratory acidosis (
D. Respiratory acidosis.
The correct answer is choice D. Shallow respirations and a respiratory rate of 9/min indicate hypoventilation, leading to an accumulation of CO2 in the blood. This condition results in respiratory acidosis, where the arterial pH is decreased. The body's compensatory response is to retain bicarbonate to normalize pH, but this can result in an elevated HCO3- level. The primary acid-base imbalance in this case is respiratory acidosis. .

Full Explanation
Choice A rationale:
A respiratory rate of 9/min and shallow respirations are indicative of hypoventilation, which can lead to an accumulation of carbon dioxide (CO2) in the blood. This condition results in respiratory acidosis (Choice D). In respiratory acidosis, the arterial pH is decreased (acidic) while the PaCO2 (partial pressure of carbon dioxide) is elevated.
Choice B rationale:
Respiratory alkalosis (Choice B) is characterized by a low PaCO2 and an elevated pH due to hyperventilation. Shallow respirations and a respiratory rate of 9/min do not align with this condition, as it typically involves rapid and deep breathing.
Choice C rationale:
Metabolic alkalosis (Choice C) results from a primary excess of bicarbonate (HCO3-) in the blood and is not associated with the given respiratory patterns. Shallow respirations and a low respiratory rate are more likely to lead to an accumulation of CO2, causing respiratory acidosis (Choice D).
Choice D rationale:
The correct answer is choice D. Shallow respirations and a respiratory rate of 9/min indicate hypoventilation, leading to an accumulation of CO2 in the blood. This condition results in respiratory acidosis, where the arterial pH is decreased. The body's compensatory response is to retain bicarbonate to normalize pH, but this can result in an elevated HCO3- level. The primary acid-base imbalance in this case is respiratory acidosis. .

A nurse is collecting data from a client who is having an acute asthma exacerbation.
When auscultating the client's chest, the nurse should expect to hear which of the following sounds?
A. Fine rales.
Fine rales Fine rales, also known as crackles, are typically associated with conditions like pulmonary edema, pneumonia, or interstitial lung diseases. These sounds are often described as "crackling" or "popping" and are heard during inspiration. In an acute asthma exacerbation, expiratory wheezing is more characteristic than fine rales.
B. Rhonchi.
Rhonchi Rhonchi are continuous, low-pitched sounds that can be heard in conditions like chronic obstructive pulmonary disease (COPD) or bronchitis. They are typically present during both inspiration and expiration. In an acute asthma exacerbation, you would expect to hear wheezing during expiration, which is different from the characteristics of rhonchi.
C. Expiratory wheeze.
D. Pleural friction rub.
Pleural friction rub Pleural friction rub is a grating, leathery sound caused by the inflamed pleura rubbing against each other. It is typically heard during both inspiration and expiration and is associated with conditions like pleuritis or pleurisy. It is not commonly associated with acute asthma exacerbation. Now, let's move on to the next question.

A nurse is collecting data from an older adult who is postoperative and receiving IV therapy at 125 mL/hr. The nurse should identify that which of the following findings indicates the client is experiencing fluid volume overload? (Select all that apply.).
A. Crackles in lung bases.
Crackles in lung bases Crackles in the lung bases are often indicative of fluid accumulation in the lungs, which can occur in conditions like heart failure. These crackles are discontinuous and sound like "fine rales.”. They can be heard during inspiration and expiration.
B. Periorbital edema.
Periorbital edema Periorbital edema, or swelling around the eyes, can be a sign of fluid volume overload, especially in the context of an older adult receiving IV therapy. It suggests that excess fluid is accumulating in the body.
C. Swelling at the IV site.
Swelling at the IV site Swelling at the IV site can be a local reaction and may not necessarily indicate fluid volume overload unless it is associated with other systemic signs.
D. Bounding radial pulse.
Bounding radial pulse A bounding radial pulse is a sign of increased stroke volume and can occur when the heart is working harder to pump the increased blood volume associated with fluid overload.
E. Flat neck veins when supine.
Flat neck veins when supine Flat neck veins when the client is supine are not typically associated with fluid volume overload. In fact, flat neck veins are more characteristic of hypovolemia. Now, let's address the final question.

During a change-of-shift report, a nurse sees that a client's IV bag of 0.9% sodium chloride has 900 mL of fluid left in it. The nurse makes rounds 30 minutes later and notes that the IV bag is empty.
Which of the following actions should the nurse take?
A. Check the client's respiratory rate and lung sounds.
Check the client's respiratory rate and lung sounds When an IV bag is unexpectedly empty, it is important to assess the client for potential complications, especially if the client was receiving fluid therapy. Checking the respiratory rate and lung sounds is essential to ensure there are no signs of respiratory distress, such as crackles or wheezing, which could indicate fluid overload or a pulmonary issue.
B. Request NPO status for the client.
Request NPO status for the client Requesting nothing by mouth (NPO) status is not the immediate action required when an IV bag is empty. The priority is to assess the client's condition and address any potential issues first.
C. Elevate the head of the bed to high Fowler's.
Elevate the head of the bed to high Fowler's Elevating the head of the bed to high Fowler's is a measure to assist with preventing aspiration during oral intake. It is not the primary action required in this situation, where assessing the client's respiratory and fluid status is more important.
D. Measure the client's temperature.
Measure the client's temperature Measuring the client's temperature is not the immediate priority in this scenario. Assessing the client's respiratory and fluid status is more critical to identify any potential issues associated with the empty IV bag. .
