1. Which of the following glands found in the skin secretes a liquid called Sebum?

• A. Apocrine Glands
• B. Sebaceous Glands
• C. Lacrimal Glands
• D. Sweat Glands

Correct answer: B

Rationale: Sebum is a liquid secreted by glands in the skin known as sebaceous glands. Sebum's primary function is to lubricate the skin and help maintain its integrity. Apocrine glands secrete a different type of sweat that is odorless but can develop an odor when combined with bacteria on the skin. Lacrimal glands produce tears to keep the eyes moist, and sweat glands secrete sweat to regulate body temperature through evaporation. Therefore, the correct answer is Sebaceous Glands because they specifically secrete sebum, distinguishing them from the other gland types mentioned.

2. To prevent a Valsalva maneuver in a client recovering from an acute myocardial infarction, the nurse would:

• A. Assist the client in using the bedside commode.
• B. Administer stool softeners daily as prescribed.
• C. Administer antidysrhythmics prn as ordered.
• D. Maintain the client on strict bed rest.

Correct answer: B

Rationale: Administering stool softeners daily is crucial to prevent straining during defecation, which can lead to the Valsalva maneuver. Straining can increase intrathoracic pressure, decrease venous return to the heart, and reduce cardiac output, potentially worsening the client's condition. If constipation occurs, the use of laxatives may be necessary to avoid straining. Administering antidysrhythmics on an as-needed basis is not indicated for preventing the Valsalva maneuver; they are used to manage dysrhythmias. Strict bed rest is not necessary and may lead to complications such as deconditioning, DVT, and respiratory issues in the absence of specific medical indications.

3. Which of these findings indicate that a pump to deliver a basal rate of 10 ml per hour plus PRN for pain breakthrough for a morphine drip is not working?

• A. The client complains of discomfort at the IV insertion site
• B. The client states 'I just can't get relief from my pain.'
• C. The level of the drug is 100 ml at 8 AM and is 80 ml at noon
• D. The level of the drug is 100 ml at 8 AM and is 50 ml at noon

Correct answer: C

Rationale: The correct answer is that the level of the drug is 100 ml at 8 AM and is 80 ml at noon. With a basal rate of 10 mL per hour, a total of 40 mL should have been infused by noon, leaving only 60 mL in the container. Any amount greater than 60 mL at noon indicates that the pump is not functioning properly. Therefore, the finding of 80 mL at noon suggests the pump is not delivering the expected medication volume. Choices A and B are related to the client's symptoms and may indicate the need for pain management assessment but do not specifically indicate pump malfunction. Choice D, where the level drops to 50 mL at noon, would actually indicate that the pump is working effectively, as the expected volume has been delivered.

4. A client in the ICU has been intubated and placed on a ventilator. The physician orders synchronous intermittent mandatory ventilation (SIMV). Which statement best describes the work of this mode of ventilation?

• A. The ventilator delivers a set rate and tidal volume regardless of whether the client is attempting to breathe
• B. The ventilator coordinates delivered breaths with the client's respiratory efforts
• C. The ventilator provides a supplemental breath for every third breath of the client
• D. The ventilator provides breaths during the expiratory phase of the client's respirations

Correct answer: B

Rationale: Synchronous intermittent mandatory ventilation (SIMV) is a ventilation mode that coordinates delivered breaths with the client's own respiratory efforts. This mode allows the client to initiate breaths, with the ventilator providing preset breaths at a controlled rate and volume. Option A is incorrect because in SIMV, the ventilator syncs with the client's respiratory efforts. Option C is incorrect as it does not accurately depict the way SIMV works. Option D is also incorrect as SIMV does not specifically provide breaths during the expiratory phase of the client's respirations. Therefore, the correct answer is B, where the ventilator coordinates breath delivery with the client's breathing efforts.

5. The nurse analyzes the results of a patient's arterial blood gases (ABGs). Which finding would require immediate action?

• A. The bicarbonate level (HCO3) is 31 mEq/L
• B. The arterial oxygen saturation (SaO2) is 92%
• C. The partial pressure of CO2 in arterial blood (PaCO2) is 31 mm Hg
• D. The partial pressure of oxygen in arterial blood (PaO2) is 59 mm Hg

Correct answer: D

Rationale: While all the values are abnormal, the low PaO2 level of 59 mm Hg indicates that the patient is at a critical point on the oxyhemoglobin dissociation curve. At this level, a small decrease in PaO2 can lead to a significant drop in oxygen saturation and compromise tissue oxygenation. Therefore, immediate intervention is necessary to improve the patient's oxygenation status. Choice A (HCO3 of 31 mEq/L) may indicate metabolic alkalosis or compensation for respiratory acidosis; however, it does not require immediate action in this scenario. Choice B (SaO2 of 92%) is slightly low but not critically low to require immediate action. Choice C (PaCO2 of 31 mm Hg) is within the normal range and does not indicate immediate danger to the patient.
