1. A client goes to the Emergency Department with acute respiratory distress and the following arterial blood gases (ABGs): pH 7.35, PCO2 40 mmHg, PO2 63mmHg, HCO3 23, and oxygenation saturation (SAO2) 93%. Which of the following represents the best analysis of the etiology of these ABGs?

A. tuberculosis (TB)
B. pneumonia
C. pleural effusion
D. hypoxia

Correct answer: D

Rationale: A combined low PO2 and low SAO2 indicates hypoxia. The pH, PCO2, and HCO3 are normal. ABGs are not necessarily altered in TB or pleural effusion. In pneumonia, the PO2 and PCO2 might be low because hypoxia stimulates hyperventilation, but the best analysis in this case is hypoxia due to the combination of low PO2 and low SAO2.

2. Which of the following is an inappropriate item to include in planning care for a severely neutropenic client?

A. Transfuse neutrophils (granulocytes) to prevent infection.
B. Exclude raw vegetables from the diet.
C. Avoid administering rectal suppositories.
D. Prohibit vases of fresh flowers and plants in the client's room.

Correct answer: A

Rationale: The correct answer is to transfuse neutrophils (granulocytes) to prevent infection. Granulocyte transfusion is not routinely indicated to prevent infection in neutropenic clients. While neutrophils are essential in fighting infections and are beneficial in selected populations of infected, severely granulocytopenic clients who do not respond to antibiotics and are expected to experience prolonged suppression of granulocyte production, routine granulocyte transfusion is not recommended. Choices B, C, and D are appropriate interventions for a severely neutropenic client. Prohibiting fresh flowers and plants helps reduce the risk of exposure to environmental pathogens. Avoiding rectal suppositories minimizes the risk of introducing harmful bacteria. Excluding raw vegetables from the diet reduces the likelihood of foodborne infections.

3. Which type of cells secrete insulin?

A. alpha cells
B. beta cells
C. CD4 cells
D. helper cells

Correct answer: B

Rationale: Beta cells are responsible for secreting insulin. Insulin is produced by beta cells in the pancreas and plays a crucial role in regulating blood sugar levels. Alpha cells secrete glucagon, not insulin (Choice A). CD4 cells are a type of immune cell that helps coordinate the immune response (Choice C). Helper cells are a type of immune cell that aids in activating other immune cells (Choice D). Therefore, the correct answer is beta cells.

4. A nurse assesses an 83-year-old female's venous ulcer for the second time that is located near the right medial malleolus. The wound is exhibiting purulent drainage, and the patient has limited mobility in her home. Which of the following is the best course of action?

A. Encourage warm water soaks to the right foot.
B. Notify the case manager of the purulent drainage.
C. Determine the patient's pulse in the right ankle.
D. Recommend increased activity to reduce the purulent drainage.

Correct answer: A

Rationale: The correct course of action is to encourage warm water soaks to the right foot. This can help promote wound healing and alleviate discomfort. Before recommending increased activity or notifying additional team members, it is crucial to assess arterial blood flow by determining the patient's pulse in the right ankle. Poor arterial blood flow could worsen the condition, making increased activity inappropriate. While notifying the case manager of purulent drainage is important, addressing the wound care directly should be the primary focus at this stage.

5. Which hormone is responsible for amenorrhea in the pregnant woman?

A. Progesterone
B. Estrogen
C. Follicle-stimulating hormone (FSH)
D. Human chorionic gonadotropin (hCG)

Correct answer: A

Rationale: Correct! Progesterone is the hormone responsible for amenorrhea in pregnant women. Progesterone plays a crucial role in maintaining the uterine lining for implantation and supporting early pregnancy. High levels of progesterone during pregnancy suppress the normal menstrual cycle, leading to amenorrhea. Estrogen, FSH, and hCG do not directly cause amenorrhea in pregnant women. Estrogen is involved in the development of female secondary sexual characteristics, FSH is involved in the growth and maturation of ovarian follicles, and hCG is produced by the placenta to support the production of progesterone during pregnancy.
