A client is receiving treatment for hypertension. Which of these findings would be most concerning to the nurse?

A. A heart rate of 90 beats per minute

B. A blood pressure of 120/80 mm Hg

C. A respiratory rate of 16 breaths per minute

D. A temperature of 98.6 degrees Fahrenheit

Correct Answer: C
Rationale: The correct answer is C. A respiratory rate of 16 breaths per minute is within normal limits; however, changes in breathing patterns can indicate respiratory distress, which is concerning, especially in a client receiving treatment for hypertension. A heart rate of 90 beats per minute may not be alarming if the client is at rest. A blood pressure of 120/80 mm Hg is within the normal range for a healthy adult. A temperature of 98.6 degrees Fahrenheit is also considered normal, showing no immediate cause for concern in this scenario.

A client with a history of asthma is admitted to the emergency department with difficulty breathing. Which of these assessments is the highest priority for the nurse to perform?

• A. Auscultation of breath sounds
• B. Measurement of peak expiratory flow
• C. Observation of the client's use of accessory muscles
• D. Assessment of the client's skin color

Correct Answer: A
Rationale: Auscultation of breath sounds is the highest priority assessment in a client with a history of asthma experiencing difficulty breathing. It helps the nurse evaluate the severity of the asthma exacerbation by listening for wheezing, crackles, or decreased breath sounds. This assessment guides treatment decisions, such as administering bronchodilators or oxygen therapy. Measurement of peak expiratory flow, although important in assessing asthma severity, may not be feasible in an emergency situation where immediate intervention is needed. Observation of accessory muscle use and assessment of skin color are also important assessments in asthma exacerbation, but auscultation of breath sounds takes precedence in determining the need for urgent interventions.

A client is receiving total parenteral nutrition (TPN). Which of these interventions should the nurse perform to reduce the risk of infection?

• A. Changing the TPN tubing and solution every 24 hours
• B. Monitoring the TPN infusion rate closely
• C. Keeping the head of the bed elevated
• D. Ensuring the solution is at room temperature before infusing

Correct Answer: A
Rationale: The correct answer is to change the TPN tubing and solution every 24 hours to reduce the risk of infection. This practice helps prevent microbial growth and contamination in the TPN solution. Monitoring the infusion rate closely (choice B) is important for preventing metabolic complications but does not directly reduce the risk of infection. Keeping the head of the bed elevated (choice C) is beneficial for preventing aspiration in feeding tube placement but is unrelated to reducing infection risk in TPN. Ensuring the solution is at room temperature before infusing (choice D) is essential for patient comfort and preventing metabolic complications but does not specifically address infection risk reduction.

A client with chronic obstructive pulmonary disease (COPD) is experiencing dyspnea. Which of these actions should the nurse perform first?

• A. Administer oxygen therapy
• B. Encourage the client to perform deep breathing exercises
• C. Raise the head of the bed
• D. Check the client's oxygen saturation level

Correct Answer: D
Rationale: The correct answer is to check the client's oxygen saturation level first. This action is crucial in assessing the severity of dyspnea and determining the necessity for oxygen therapy. Administering oxygen therapy without knowing the current oxygen saturation level can be inappropriate and potentially harmful. Encouraging deep breathing exercises and raising the head of the bed are important interventions, but assessing the oxygen saturation level takes precedence in managing dyspnea in a client with COPD.

A client who is pregnant and has hyperemesis gravidarum is being taught about nutrition at home by a nurse. Which of the following statements indicate that the client understands the teachings?

• A. I will drink water with my meals.
• B. I will eat every 6 hours throughout the day.
• C. I will eat crackers before I get out of bed in the morning.
• D. I will limit my protein intake.

Correct Answer: C
Rationale: The correct answer is C. Eating crackers before getting out of bed can help manage nausea associated with hyperemesis gravidarum. Choice A is incorrect because drinking water with meals may exacerbate nausea. Choice B is incorrect as eating every 6 hours may not be frequent enough to combat nausea and vomiting. Choice D is incorrect because protein intake should not be limited during pregnancy, especially in cases of hyperemesis gravidarum.
