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.

The nurse is counting a client's respiratory rate. During a 30-second interval, the nurse counts six respirations, and the client coughs three times. In repeating the count for a second 30-second interval, the nurse counts eight respirations. Which respiratory rate should the nurse document?
- A. 14
- B. 16
- C. 17
- D. 28
Correct Answer: B
Rationale: The most accurate respiratory rate is the second count obtained by the nurse, which was not interrupted by coughing. The nurse counted eight respirations over 30 seconds, so doubling this count gives a respiratory rate of 16 breaths per minute. This calculation is based on the assumption that the client's breathing pattern remained relatively stable during the two 30-second intervals. Options A, C, and D are incorrect because they do not reflect the accurate count obtained without interruptions. Choice B (16) is the correct answer as it reflects the uninterrupted count of respirations by the nurse.
The major difference between a grand mal and petit mal seizure is that a person with a grand mal seizure will have _______________ and the person with a petit mal seizure will not.
- A. convulsive movements
- B. sleep apnea
- C. atonic movements
- D. flaccidity
Correct Answer: A
Rationale: The major difference between a grand mal and petit mal seizure is the presence or absence of convulsive movements. Grand mal seizures are characterized by convulsive movements, including jerking of limbs and loss of consciousness. In contrast, petit mal seizures, also known as absence seizures, typically involve brief episodes of staring or eye blinking without convulsive movements. Therefore, choice A, 'convulsive movements,' is the correct answer. Choices B, 'sleep apnea,' and D, 'flaccidity,' are incorrect as they are not associated with the characteristics of grand mal or petit mal seizures. Choice C, 'atonic movements,' is also incorrect as petit mal seizures do not involve atonic movements, but rather absence behaviors such as staring spells.
The nurse is performing a neurological assessment on a client post right cerebrovascular accident. Which finding, if observed by the nurse, would warrant immediate attention?
- A. Decrease in level of consciousness
- B. Loss of bladder control
- C. Altered sensation to stimuli
- D. Emotional lability
Correct Answer: A
Rationale: A decrease in the level of consciousness is a critical finding that would warrant immediate attention in a client post right cerebrovascular accident. This change may indicate an increase in intracranial pressure, leading to inadequate oxygenation of the brain. It could also reveal the presence of a transient ischemic attack, which may signal an impending thrombotic cerebrovascular accident. Loss of bladder control (choice B) can be managed and monitored but does not indicate an immediate threat to the client's life. Altered sensation to stimuli (choice C) can be a concerning finding but may not require immediate attention unless it affects the client's safety. Emotional lability (choice D) may be distressing for the client but does not pose an immediate risk to their health compared to a decrease in the level of consciousness.
The mother of a child with hepatitis A tells the home care nurse that she is concerned because the child's jaundice seems worse. What is the nurse's best response?
- A. You need to change the child's diet.
- B. The child probably is infectious again.
- C. The jaundice may worsen before it resolves.
- D. You need to call the primary health care provider.
Correct Answer: C
Rationale: The best response for the nurse in this situation is to explain to the mother that jaundice may seem to worsen before it eventually gets better. This is a common occurrence in hepatitis A. Option A about changing the child's diet is irrelevant to the concern raised by the mother and not supported by evidence. Option B suggesting the child is infectious again is incorrect and may cause unnecessary alarm as jaundice does not indicate reinfection. Option D, advising the mother to call the primary health care provider, is premature as the nurse can first provide education and reassurance regarding the expected course of jaundice in hepatitis A.
What is the cause of meningitis that is fatal in half of the infected patients?
- A. Virus
- B. Bacteria
- C. Fungus
- D. Noninfectious agent
Correct Answer: B
Rationale: Bacterial meningitis is caused by bacterial pathogens such as Streptococcus pneumoniae, Haemophilus influenzae, Listeria monocytogenes, and Neisseria meningitidis. These bacteria commonly lead to acute onset meningitis, presenting with symptoms like fever, stiff neck, and altered consciousness. The statement that bacterial meningitis is fatal in about 50% of cases is accurate, making it a serious and life-threatening condition. Viruses can also cause meningitis, but they are not typically associated with the high fatality rate seen in bacterial meningitis. Fungal meningitis is less common and usually affects individuals with weakened immune systems. Noninfectious agents do not cause meningitis.
