Question 1 of 5
A nurse is providing postoperative care to a client who lost 800 mL of blood during surgery. The client's blood pressure has been steadily decreasing over the past 2 hours. Which of the following categories of shock should the nurse recognize is occurring?
Correct Answer: C
Rationale: Blood loss of 800 mL causes hypovolemic shock, leading to decreased blood pressure. Other shocks involve different mechanisms.
Question 2 of 5
A nurse is monitoring a client who received epinephrine for angioedema after a first dose of losartan. Which of the following data indicates a therapeutic response to the epinephrine?
Correct Answer: C
Rationale: Unlabored respirations indicate improved airway patency, a key effect of epinephrine. Other options are not specific to angioedema treatment.
Question 3 of 5
A nurse is teaching a client who has septic shock about the development of disseminated intravascular coagulation (DIC). Which of the following statements should the nurse make?
Correct Answer: C
Rationale: DIC involves abnormal coagulation, consuming fibrinogen and platelets, causing clots and bleeding. Platelet counts drop, heparin is not lifelong, and DIC is not genetic.
Question 4 of 5
A client is admitted to the emergency room with a respiratory rate of 7/min. Arterial blood gases (ABG) reveal the following values. Which of the following is an appropriate analysis of the ABGs? pH 7.22, PaCO2 68 mm Hg, Base excess -2, PaO2 78 mm Hg, Saturation 80%, Bicarbonate 26 mEq/L
Correct Answer: A
Rationale: Low pH (7.22) and high PaCO2 (68 mm Hg) with normal bicarbonate indicate respiratory acidosis due to hypoventilation. Other options do not match.
Question 5 of 5
A nurse is educating a client who has HIV about the infection process. Which of the following features of the virus should the nurse explain can result in opportunistic infection?
Correct Answer: D
Rationale: HIV’s destruction of CD4 lymphocytes causes immunosuppression, leading to opportunistic infections. Other features enable replication but don’t directly cause infections.
